ALFOSC Sequencer Command Documentation

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	autoshow_off	[-d]	Turns off the automatic image display while reading out. If 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	display	[<file>]	Loads an image into the ALFOSC DS9 display. If no <file> is specified, the last image obtained will be loaded. If no DS9 display exists, one will be started.	DISP
alfosc	display-start		Starts an empty ALFOSC DS9 display.	DISP
alfosc	ds9-for-mos		This script start a dedicated DS9 display that is used for MOS tweaking	DISP
alfosc	hicut	<value>	Applies a minmax scaling to the loaded DS9 image and set the highcut to <value>.	DISP
alfosc	killdisplay		Terminates all instances of the ALFOSC DS9 display.	DISP
alfosc	killimexam		Terminates all ALFOSC sequencer scripts related to imexam and the ALFOSC DS9 display.	DISP
alfosc	locut	<value>	Applies a minmax scaling to the loaded DS9 image and set the lowcut to <value>.	DISP
alfosc	overlay	[yes|no]	Overlays the loaded DS9 image with seeing information and marks saturated objects.	DISP
alfosc	setdisplay	[<Xserver>]	Set the X server on which the DS9 window will be displayed. If no <X server> is specified, the server from which the command is issued will be used. Note that the X server must allow for remote connections (use 'xhost').	DISP
alfosc	wcs-align	[yes|no]	Display the loaded image using world coordinates such that North is up. Called with the [no] option, the image is aligned according to orientation on the detector.	DISP
alfosc	zscale		Sets the upper and lower limits of the loaded image based on the IRAF ZScale algorithm. (Displays the image values near the median image value).	DISP

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:
