System | Command | Arguments | Description | Type |
alfosc |
abort |
[-d] |
Aborts an ongoing exposure. |
DET |
alfosc |
acquisition |
[-c] [-q] [-nofo] <slit> <tt> |
Script for ALFOSC-spectroscopy target acquisition for slit <slit> using exposure time <tt>. If optional flag -c is used, a check image of the star on the slit is made. If optional flag -q is used, the user is queried for another iteration. The -nofo flag should be used if no automatic focus-offset should be set. |
TEL |
alfosc |
allopen |
[-e] |
Moves all ALFOSC/FASU optical wheels to the OPEN position. |
INST |
alfosc |
autoshow_off |
[-d] |
Turns off the automatic image display while reading out. If a DS9 is running it will be terminated. |
DISP |
alfosc |
autoshow_on |
[-d] |
Turns on the automatic image display while reading out. If no DS9 is running one will automatically be started. |
DISP |
alfosc |
calibexp |
[-e] [-f] [-n <nn>] [-o <ObjName>] [-lmi] <lampID> <tt> |
Sets ALFOSC calibration items up for a calibration spectrum with lamp <lampID>, take <nn> calibration images of exposure time <tt>, switch off lamps and, if not -lmi is given, take out mirror. With <lampID>=He/Ne/HeNe/ThAr/Halogen . |
DET |
alfosc |
dark |
[-d] [-t] [-f] [-n]<tt> |
Makes a dark exposure of <tt> seconds. If <tt> is set to zero a BIAS exposure is made.
If the exposure time is larger then 60 seconds, automatic remnant removal is done before the exposure starts.
If the option [-f] (fast mode) is used, the prompt will be returned when the exposure time is over and before the readout begins.
If the option [-n] is used, there will be no automatic remnant removal. |
DET |
alfosc |
display |
[<file>] |
Loads the image <file> into the ALFOSC DS9 display. If no file is specified, the last image obtained will be loaded. |
DISP |
alfosc |
expose |
[-d] [-t] [-f] [-n]<tt> |
Makes an exposure of <tt> seconds.
Remnant removal is made before the exposure starts, if the exposure time is larger then 60 seconds. If the option [-n] is used, no remnant removal is done.
If the option [-f] (fast mode) is used, the prompt will be returned when the exposure time is over and before the readout begins. If [-f] is used, make sure that "alfosc.wait-camera-state idle"-command is given before any "alfosc_camera_commands".
If the exposure time is larger than 300 seconds, the time left until the rotator reaches its limit will be checked. If there is not time enough to complete the exposure, an error will be generated and the exposure will not start. |
DET |
alfosc |
focus |
[-e] [-n <N>] [-nodefault] [-t <nn>] [-a <mode>][-filter] |
Focuses the telescope. [-n <N>] makes <N> loops. [-t <nn>] sets exposure time to <nn> . [-nodefault] starts from current focus. [-a <mode>] acquisition using <mode>. |
TEL |
alfosc |
focus-offset |
[-e] [-d <nn>] |
Applies focus offset for optical elements in the light beam. If no offset is known a value of 0 will be assumed. Use [-d] flag to defocus the telescope with <nn> units.
|
TEL |
alfosc |
imexam |
|
Initiates an IRAF imexam session on the loaded DS9 image. |
DATA |
alfosc |
lamp |
[-d] [position] <n> <m> |
Turns on/off lamp number <n>, <m>=1 is turn on, <m>=0 is turn off. [position] returns a 4 bit pattern corresponding to the state of the 4 lamps. |
INST |
alfosc |
log-comment |
"Comment in quotes" [file1 file2 ...] |
Set a comment in the last image (or the specified ones, if any) using the LOGCOMME keyword |
DATA |
alfosc |
mdark |
[-t] [-n] [-f]<tt> <nn> |
Makes <nn> dark exposures of <tt> seconds. If the [-t] flag is used, a simulated exposure is made. If the exposure time is larger then 60 seconds, automatic remnant removal is done before the exposure starts. If the option [-f] (fast mode) is used, the prompt will be returned when the exposure time is over and before the readout begins. If the option [-n] is used, there will be no automatic remnant removal. |
DET |
alfosc |
mexpose |
[-t] [-n] [-f]<tt> <nn> [<imtype>] |
Makes <nn> exposures of <tt> seconds.
Remnant removal is made before the exposure starts, if the exposure time is larger then 60 seconds. If the option [-n] is used, no remnant removal is done. If the option [-f] (fast mode) is used, the prompt will be returned when the exposure time is over and before the readout begins. If [-f] is used, make sure that "alfosc.wait-camera-state idle"-command is given before any "alfosc_camera_commands". If the exposure time is larger than 300 seconds, the time left until the rotator reaches its limit will be checked. If there is not time enough to complete the exposure, an error will be generated and the exposure will not start.
