Instrument	: ALFOSC
Observing Mode	: ANY IMA SPEC POL
Command Type	: ANY DATA DET DISP INST TEL
Usage	: BASIC GENERAL STAFF
Description	: SHORT LONG

System	Command	Arguments	Description	Type
alfosc	imexam		Initiates an IRAF imexam session on the image currently loaded into the ALFOSC DS9. While active in the imexam session, no further commands can be issued from the sequencer window. To kill the imexam session type q on the image in the postprocessing display. CURSOR KEY COMMANDS: ? Print help a Aperture radial photometry measurement (see above for output) c Column plot e Contour plot f Redraw the last graph j Fit 1D gaussian to image lines k Fit 1D gaussian to image columns l Line plot m Statistics image[section] npixels mean median stddev min max q Quit r Radial profile plot (see above for output) s Surface plot x Print coordinates col line pixval [xorign yorigin dx dy r theta]	DATA
alfosc	log-comment	"Comment in quotes" [file1 file2 ...]	When invoked with just the comment, it will be applied to the latest available image with a prefix for the current night (which starts at noon) and the sequencer's instrument. If image names are provided, the program will test the existence of ALL them before applying the change. Eg. $ alfosc.log-comment "This is a comment" $ alfosc.log-comment "Comment for two" ALug170154 ALug170155 Notice that there's no need to add the ".fits" after each image's name If no arguments are provided, a usage message is displayed	DATA
alfosc	object	[-d] <text>	Sets the FITS keyword OBJECT to <text>.	DATA
alfosc	qicpol	[<2ndfile>]	Circular polarimetry quick-look tool (FAPOL+ calcite) which calculates the circular polarization from a set of two images (retarder plate positions 0 and 90.0 degrees). The flux of each image is measured with fixed aperture using iraf/apphot from raw images. See more detailed description of the script from here	DATA
alfosc	qilpol	[<4thfile>]	Linear polarimetry quick-look tool (FAPOL+ calcite) which calculates the linear polarization from a set of four images (retarder plate positions 0, 22.5 45 and 67.5 degrees). The flux of each image is measured with fixed aperture using iraf/apphot from raw images. See more detailed description of the script from here.	DATA
alfosc	rempath	[-d] <nn>	Sets the remote saving path to <nn>.	DATA
alfosc	remsave_off	[-d]	Turns off remote saving.	DATA
alfosc	remsave_on	[-d]	Turns on remote saving.	DATA
alfosc	reset-log		The script will use infosys.kill to reset the monitoring system, then it will wait for a set number of seconds, and at last it will instruct the obslog to show the listing for alfosc, all the while informing the user about what is happening If there's any error, the script will notify the user and suggest further actions.	DATA

In scripts, the syntax alfosc.<command> should be used.
If a part of a command is written in <angle brackets>, this is an argument that should be replaced with a value.
If a part of a command is written in [square brackets], this is an optional argument or flag.
When available, the optional flag -d will write extended debugging information to the log.
When available, the optional flag -e will show the script on standard output instead of executing the commands.
When available, the optional flag -t will only make a simulated exposure. Useful for testing scripts.

Type definitions:
DATA: All commands related to handling/modifying data (editing fits-headers, post-processing etc.).
DET: Commands related to operations with the detector.
DISP: Commands related to displaying images on the instrument computer.
INST: Commands related to operations with the instrument.
TEL: Commands related to operations with the telescope.
