||[-d] [pos] [ready] [action]
||Moves FAPOL carriage in or out with the [action] keyword. [action] can be 'in', 'IN', 'out' or 'OUT'. [pos] returns '1' if the carriage is in the lightpath, '0' if it is out. [ready] returns '0' if the element is moving, '1' if it is ready.
||[-d] [position] <n> <m>
||Turns on/off lamp number <n>, <m>=1 is turn on, <m>=0 is turn off. [position] returns a 4 bit pattern corresponding to the state of the 4 lamps.
||[-d] [pos] [ready] <n>
||Moves the polarizer to angle <n>, where <n> is any multiple of 22.5 between '0' and '337.5'. [pos] returns the current polarizer position. [ready] returns '0' if the element is moving, '1' if it is ready.
||[-e] [-s <slit>] [-g <grism>] [-c <crossdisp>] [-f <filterID>] [-d <diffuserID>][-nowait] [-forceFASU]
||Sets all 5 ALFOSC wheels to the given setup. Default is OPEN. If optional flag -nowait is used, the script exits while wheels are moving.
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.
