||Exits the ALFOSC BIAS program.
||[-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.
||Turns off autosave.
||Turns on autosave.
||Computes the best focus value from a focus sequence image taken with the command focusexpose. If no image name <image> is given, the last obtained image will be used. The computed focus value is not automatically sent to the TCS.
||[-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.
||Computes detector gain and read-out-noise based on a sequence of two bias frames and two flat fields. The filename <file> must be the last in the sequence. If no filename is given, the last obtained image name will be used. Calculated values are being compared to previous values before being uploaded to database. If the deviations from previous results are found to be too large, the script can be terminated without uploading results.
||Takes a sequence of two bias frames and two flat fields with the betalight for each amplifier and gain setting and calls gainron to calculate gain and read-out-noise.
||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.
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.
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.
