System | Command | Arguments | Description | Type |
alfosc |
abort |
[-d] |
Aborts an ongoing exposure. |
DET |
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 |
cirpolexpose |
[-e] <Nang> <ObjName> <tt> <Ncyc> [-nowindow] |
Sets up and executes a set of circular polarimetry imaging exposures with <Nang> angles, exposure time <tt> and <Ncyc> cycles. If optional argument -nowindow is used, no windowing is applied. |
DET |
alfosc |
cirpolspec |
[-e] <Nang> <ObjName> <tt> <Ncyc> |
Sets up and executes a set of circular polarimetry spectroscopy exposures with <Nang> angles, exposure time <tt> and <Ncyc> cycles. |
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 |
dither |
[-e] [-t] [-nowakeup] <pattern> <offset_size> <tt> |
Takes single exposures with exposure time <tt> at each pointing of the dither pattern <pattern> with offset <nn> arcseconds between each exposure. |
DET |
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 |
linpolexpose |
[-e] [-nowakeup] [-std] <Nang> <ObjName> <tt> <Ncyc> [-nowindow] |
Sets up and executes a set of linear polarimetry imaging exposures with <Nang> angles, exposure time <tt> and <Ncyc> cycles. If optional argument -nowindow is used, no windowing is applied. |
DET |
alfosc |
linpolspec |
[-e] [-nowakeup] [-std] <Nang> <ObjName> <tt> <Ncyc> |
Sets up and executes a set of linear polarimetry spectroscopy exposures with <Nang> angles, exposure time <tt> and <Ncyc> cycles. |
DET |
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.

DET |
alfosc |
polwin |
|
Windows the readout, optimized for imaging polarimetry. |
DET |
alfosc |
readout |
[-d] |
Closes the shutter and readout the ccd. The exposure must first be put in the background. Does not work correctly when using a window in Y direction. |
DET |
alfosc |
readspeed |
[-d] <readout_speed> |
Sets the CCD readout speed to <readout_speed> kpix/second. Valid values for <readout_speed> are 100, 200, 400 or 800. |
DET |
alfosc |
remove_remnants |
|
Remove remnants from the CCD |
DET |
alfosc |
resetxy |
[-d] |
Resets the ccd binning to 1, the X and Y size to maximum and the X and Y beginning to 1. |
DET |
alfosc |
simpolexpose |
[-e] [-nowakeup] [-std] <Nang> <ObjName> <tt> <Ncyc> [-nowindow] |
Sets up and executes a set of simultaneous linear and circular polarimetry (using lambda/4 retarder) imaging exposures with <Nang> angles, exposure time <tt> and <Ncyc> cycles. If optional argument -nowindow is used, no windowing is applied. |
