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	alfosc.exit	[-d]	Exits the ALFOSC BIAS program.	DET
alfosc	alfoscfocus	[-d] [ready] [step] <n>	Moves ALFOSC internal focus to step position <n>. [ready] Returns '0' if the element is moving, '1' if it is ready. [step] returns the step position [0-2700] of the ALFOSC internal focus.	INST
alfosc	autosave_off	[-d]	Turns off autosave.	DATA
alfosc	autosave_on	[-d]	Turns on autosave.	DATA
alfosc	focus-auto	<step-size> [<image>]	Computes the best focus value from a focus sequence image <image> taken with the command focusexpose with focus step-size <step-size>. If no filename is given, the last obtained image name will be used.	DATA
alfosc	focusexpose	[-d] <nnnn> <mm> <tt>	Makes a focus exposure. <nnnnn> is the focus start value, <mm> is the step size and <tt> is the exposure time per sub-exposure. 7 sub-exposures will be made.	DET
alfosc	gainron	[<file>]	Computes detector gain and read-out-noise based on two bias frames and two flat fields, <file> being the last in the sequence. If no filename is given, the last obtained image name will be used.	DATA
alfosc	qc-script		Takes beta-light bias frames and flat fields for ALFOSC quality control. Calculates gain and read-out-noise.	DET
alfosc	read_alfosc_setup		The command instructs the ALFOSC instrument user interface (UIF) to re-read the setup information. The corresponds to pressing the "read setup" button in the UIF.	INST

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.
