Command |
Description |
AA |
Enter desired coordinates manually as altitude
and azimuth. Otherwise similar to CO. |
AM |
Toggle between mean and apparent (uncorrected)
coordinates. |
CF |
Close the currently open file. If no file is open,
the command is ignored. When the file is closed, number of entries and
descriptor are blanked and the name of the currently open file is changed
to "No file open". |
CO |
Enter desired coordinates manually. After user confirmation,
the telescope is moved to the requested position. The coordinates are assumed
to be in the current keyboard equinox. |
CS |
Close the sliding
roof shutter at the PSST. Close the instrument shutter at the 72".
|
DD |
Disable the delayed slew. This command is
passworded and only available at the 72". |
DE |
Delete ephemerides. The command may be optionally
entered as DE n. If the n is omitted, the program will prompt for it. All
ephemerides numbered n or greater are deleted |
DJ |
Dome Jog. This command may be
optionally entered as
DJ n. If n is positive, jog the dome n degrees to the right. If n is
negative, the jog is to the left. Not available at PSST and Wallace. |
DF |
DOS directory of files command. The entered string
is passed to the DOS DIR command. The string may be entered on the command
line (eg, DF A:*.EPH or DF C:\USER\*.SRC). If the string is not entered
on the command line, the program will prompt for it. |
DM |
Toggle dome following on or off. Not available
at PSST or Wallace.. |
ED |
Enable delayed slew. Allows
adjusting the cutoff for forcing a delayed
slew. The default is 15 degrees. It can be made smaller, but it
cannot be bigger. Only available at the 72". |
EE |
Enter an ephemeris for use with the EG, LE, SE and
EO commands. The command may be optionally entered as EE n. If the n is
omitted, the first call to EE allows entry of ephemeris number 1, the second
call allows entry of ephemeris number 2, etc. The optional parameter n
is used to replace an existing ephemeris (n must be less than or
equal to the number of currently entered ephemerides). Each ephemeris entry
consists of an object name; the year, month, day of the first ephemeris
point; the equinox of the ephemeris; and ephemeris times (h,m,s) and positions.
As many times/positions as desired may be entered. Up to 999 ephemerides
may be stored. Alternatively, you may provide a file containing the ephemeris.
When the object name is requested, enter @fname where fname is the file
name of the ephemeris. The file may be an output file from jplephem (ie,
a planetary ephemeris); from naifeph (ie, a satellite ephemeris); from
ef8 (ie, an asteroid ephemeris); from cef8 (ie, a comet ephemeris); or
a special ephemeris generated via IDL (see Marc Buie for details). The
program automatically determines the type of ephemeris and reads it correctly.
If you enter a "standard" ephemeris (ie, from jplephem, naifeph, cef8,
or ef8), each ephemeris file must be for only one object. The program will
extract the object name, equinox, and ephemeris information from ephemeris
points between T minus 2 hours and T plus 15 hours where This the UT time
at which the ephemeris is entered. Thus, one only needs to generate a single
data file for an entire run -- the program will extract the appropriate
part of the ephemeris for each night. The IDL output file is a special
case. This file can have multiple objects and the program will extract
the ephemeris for each object in the file for times between T-2h and T+15h.
If the input file contains enough ephemerides that adding all of them would
exceed the limit of 999 stored ephemerides, the program only stores those
which bring the number stored to 999. |
EG |
Move to a position defined at the current time by
an ephemeris previously entered via EE. The program calculates the position
of the object at the current time (a warning is generated if the position
is extrapolated from the ephemeris rather than interpolated) and requests
confirmation for the move. Once the telescope moves to the requested position,
the calculated rates and current ephemeris number are displayed on the
screen, and the telescope goes into track rate lock at those rates. |
EO |
Compute an ephemeris offset as the current position
of the telescope minus that calculated from the currently entered ephemeris.
Add this offset to all subsequent EG moves. Entering a new ephemeris with
EE zeroes the offsets. |
ER |
Manually enter a rate. The rate appears on the screen,
and is tagged with ephemeris number 0. To start tracking at the entered
rate, use the LM command. |
EX |
Toggle display equinox between date equinox and the
alternate equinox (see NE). Note that the keyboard equinox changes
with the display. |
FF |
Define the position of the fiducial
switches (HA and Dec). Not available at the Astrograph. |
FG |
Focus Go. Go to a
specific value of the focus readout, relative or absolute.
|
FI |
Re-initialize
the focus by
moving it to the home position. This command also sets the focus mode
to absolute. The home position is defined absolute zero.
|
FL |
Toggle mechanical flexure correction on and off. |
FN |
Toggle between fractional and normal display. In normal
display, the RA is, for example HH MM SS.S and in fractional it is HH MM.MM. |
FR |
Focus Relative
move.
Move to a focus
position a given number of steps from to the current position.
|
FS |
Move telescope to flat field screen position and turn
off sidereal track. If dome following is enabled, the dome is moved to
the appropriate position and then disabled. |
FT |
Focus mode
Toggle.
Toggle the focus readout between displaying the focus in absolute or
relative mode.
|
FZ |
Define current
focus position as zero (relative). That is, as 0R.
|
GS |
Get a star from the guider catalog. The program
asks if the star is to be near the current telescope position or near
some other position. If some other position, it requests that the user
enter the desired coordinates (of current keyboard equinox). Next, it requests
the magnitude range for the request (the catalog contains stars brighter
than mag 14.0). A range from 3.0 to 4.0 can be entered as 3,4 or 4,3 or
3.0,4.0 or 4.0,3.0. Entering a single value is equivalent to requesting
all stars brighter than that value.Given this information, the program
searches the catalog to find the nearest star (either to the current
telescope position or to the user-provided coordinates) which meets the
requested magnitude limit. When a star is found, the program reports the
RA and Dec (at equinox 2000.0, epoch of date) and at the
current display equinox if not 2000.0); the angular separation of the
star from the base coordinates (either the current coordinates or the requested
coordinates); and the Vmag of the star. The user then is given three choices:
Try for another star (the next nearest is found); move to the star and
then return to the menu; or return to the menu. Since the GS command replaces
the old PP command (PPM star), PP has been retained as a synonym for GS. |
HO |
Move the telescope/dome to their home position. For the
72" and 42" this location is 3
degrees east of the meridian, -3 degrees declination with the dome 80
degrees left of the telescope..
For the
31" this location is 3 degrees west of the meridian, -5 degrees declination
with the dome at an azimuth of 105 degrees.
For LONEOS
this location is on the meridian at -41 degees declination
with the dome 13 degrees right of the telescope.
For the
PSST this is 5 degreees east of the meridian at -49 degrees
declination (there is no dome).
For Wallace this is on the meridian at -43 degrees declination and the
dome is ignored.
And, for the astrograph, this is on the meridian at 12 deg 40 min
declination with the dome alligned with the telescope.
At the
42" and 72" the HOME position is that of the white marks on the setting
circles. Sidereal track
is turned off after a home.. |
HP |
Generate a help display. |
IC |
Re-initialize coordinates. If the
telescope is totally lost, one may reset the coordinates from the fiducial
switches. The program asks the user to move the telescope manually back
to the home position.
The telescope
is then automatically slewed over the switches to reset the coordinates.
The procedure is the same as performed on startup if the saved position
file is not found or if the user requested a manual startup.
This command is not available at the Astrograph.. |
ID |
Allows initialization of
the dome exactly as in the MOVE startup procedure. At the 72 inch, if the
coast initialization is skipped,
the parameters are left as they currently are defined. Only available
at the 72", LONEOS, and Astrograph. The other telescopes do not have
domes or have barcode readers and do not need this command. |
KD |
Turn off a deadman timer which might have been
turned on via a remote command. |
KE |
Change equinox of keyboard coordinates, but not display
equinox. |
KM |
Keypad (relative) move. This routine uses the numeric
keypad to do relative moves. The move is D arc seconds where D can be changed
using the keypad + and - keys and may be varied between 0.5 and 300 arcsec.
Each time the value is changed, it is flashed at the bottom of the screen.
The current value can also be shown (without changing it) with the F1 key.
The 8 key moves the telescope north; the 2 key south; the 4 key east; the
6 key west; the 7, 9, 3, and 1 key are combinations. The current step size
is retained between successive calls to KM. Type F2 to exit from KM. |
LE |
Display a list of currently entered ephemeris numbers/object
names. |
LI |
Turn dome light on/off at the 31" and 72" |
LM |
Coordinate lock mode modify. The program requests
that you enter an S to lock at sidereal rate; T to lock at track rate (using
the rates currently on the display); or O to turn lock off. The command CL is
synonymous with LM. |
LS |
Toggle light supression on/off at the 31".
Normally, the light goes on at the start of a slew and off at the
end. LS allows supressing this behavior. |
MF |
Modify mechanical flexure and/or dome offset constants. |
NE |
Enter a new alternate equinox. |
NS |
Move to the nearest star in the currently opened file.
If this star is not acceptable, move to the next nearest, etc. |
OF |
Open a coordinates file. The name of the file is requested.
Once the file is opened, the third area of the screen displays the file
name, number of entries in the file and descriptor for the file. If a path
is not specified, the file is assumed to reside on the MOVE disk in the
default user directory, C:\USER. If the file does not exist, an error message
is printed and control returns to the menu. |
OG |
Move to an object by its name (Messier NGC, IC, HR,
Bayer, Flamsteed, or common name) |
OL |
Modify/update/change an observing list file. When
in this mode, the screen is cleared of the display and the user can use
the whole screen for input and output. One may create a new file,
add entries to a file, delete entries from a file, list a file,
or modify a file. Each star entry in the file consists of a 20 character
star ID, the star's RA/DEC, proper motions or sky offset, equinox, and a 28
character comment field. If no path is specified in the file name, the
file is assumed to be in the default directory (C;\USER). Files
created before 05/22/95 do not have proper motions or sky offsets. The program
will properly distinguish between old and new style files in a way which
is transparent to the user. However, all files created after this date will
be in the new style (with proper motions or sky offsets). When a file is
created, the program asks if the file will have proper motions or sky
offsets. In any later reference to that file, the program will automatically
recognize the type. |
OS |
Open the sliding roof
shutter at PSST. Open the instrument shutter at the 72"
|
PF |
Display (print) mechanical flexure and
dome offset constants. |
PM |
Move back to any one of twenty previous positions.
Any move which the telescope makes successfully (is not aborted) is added
to the previous move table and can be returned to via the PM command. Note
that relative moves (via a KM, RM or remote relative move) are not added
to the table. The last twenty successful moves are stored in the table.
The current object name, position and equinox can be saved in the table
with the SC command. PM may be optionally entered as PM n where n is the
desired position number. Note that a PM to a previous ephemeris position
is equivalent to an EG to that object. |
QU |
Exit MOVE (confirmation is requested). Proper exit
is necessary for parameter files to be stored so that the may be used
the next time MOVE is started.. |
RE |
Do full reset of coordinates by manually setting on
a known star and entering its coordinates and equinox on the terminal.
Note that the RA/DEC of this star must be known accurately at some equinox --
the actual equinox does not matter. A limited set of MOVE commands are
accepted while within the RE command -- TR, FN, EX and NE. |
RF |
Read from the currently opened file. A star number
is requested. Appropriate error messages are generated if a file is not
currently open or if a number larger than the number of objects in the
file is requested. The computer shows the Star ID, RA, Dec, and comment
field and asks for confirmation before moving. After a move, the program
returns to the main menu. The file remains open. |
RJ |
This is a rectangular jog. This was a routine written
especially for one event using OSIRIS at the 72" and may never be used
again. |
RM |
Relative move. Allows user to enter offsets in either
of two modes: as an RA and Dec offset (in arcsec) from the current telescope
position or as a position angle and total offset from the current telescope
position. The telescope then moves to the new position. The total move
must be less than two degrees. |
RT |
Toggle remote command port on/off. It is on on
entry to MOVE. The status of this toggle is shown on the display. The
remote option is used for commanding from a remote computer.
|
SC |
Save current object name, position & equinox on
the previous move stack. |
SD |
Set the system date. If the WWV clock is running properly,
it will reset the date correctly within a minute so that this command has
no effect |
SE |
Show an ephemeris previously entered via an EE command
The name, equinox, times, positions, computed velocities, and offsets are
shown. |
SF |
Read the sky position from the currently opened file.
The sky position is that position the RF command would generate plus the
sky offset.
A star number
is requested. Appropriate error messages are generated if a file is not
currently open or if a number larger than the number of objects in the
file is requested. The computer shows the Star ID, RA, Dec, and comment
field and asks for confirmation before moving. After a move, the program
returns to the main menu. The file remains open. |
SH |
Set the coordinates of the current location to be
those of the home position for this telescope. |
SL |
SLeep. Put the telescope into sleep mode. Write
out the current coordinates, disable the paddle, most remote commands, and
the keyboard (except for the WK command to wake up). Use this command
if MOVE is left running for some time but not actually being used. |
SM |
Toggle between Sun and Moon display on screen (MS
will also do this). |
SN |
Spiral or jail bar scan. The program reqests the scan
parameters and the scan rate. Type any key or hit any paddle button to
start and then to stop. |
SR |
Allows modification of the telescope rates (sidereal,
guide, or set). The default rate for guide is 5 arcsec/sec and for set
is 50 arcsec/sec. The program allows setting the RA and Dec rates differently
or to the same value. The slew rate cannot be changed by the user. |
ST |
Set the system time. If the WWV clock is running properly,
it will reset the time correctly within a minute so that this command has
no effect. |
TF |
Toggle "flipped" mode on/off at the Astrograph.
In "flipped" mode the internal sense of north/south is reversed so
that the paddle and encoders work correctly even though the telescope
is "backwards". . |
TI |
Toggle time display between UT and MST. |
TR |
Sidereal tracking toggle. Reverses the current state
of the sidereal rate tracking each time it is entered. The current state
is indicated on the display. |
UC |
Use the coordinates of the last move (the most recent
addition to the previous move table) to update the display. The update
is made in the current display equinox, no matter what the equinox of the
last move was. The size of the update is shown on the screen. If the
update is made to a moving object, the coordinates are updated to the
computed position at the time of the update, not the position the telescope
originally moved to.
|
UI |
Move telescope to the Chromey spot (PASP, 108, 944).
This spot is supposed to have the most uniform illumination at sunset or
sunrise. It is on the Sun's meridian, 20 degrees on the opposite side of
the zenith as the sun. |
WK |
Wake up the telescope if it has been asleep. This
returns MOVE to its normal operating mode. |
ZE |
Move telescope to the zenith. If dome following
is enabled, the dome is moved to an azimuth of 180 degrees and sidereal
track is turned off. |
