setdar -- sets dar mode and tells wfao to wait/not wait for dar

NAME

setdar -- sets dar mode and tells wfao to wait/not wait for dar

OSIRIS library of scripts

SYNOPSIS

setdar mode

DESCRIPTION

sets the keyword WFDAR to on or off, telling the wfao script whether or not
to force an offload of the DAR shifts to the field steering mirrors.

if no mode is selected, script returns the current DAR settings.

setdar [on,slew,fsm,off]
option: wait4dar AODRENA AODRDTEN OBFMDREN
off off 0 0 0
slew off 1 0 1
fsm on 1 0 1
on on 1 1 1

option off:
No compensation for DAR at all, no waiting for dar from the OSIRIS side.

option slew or nod:
DAR compensation only go to the FSM when one moves the FSM. Nothing
goes to the DT ctrl offset. If one keeps integrating on a star, DAR
would NOT be applied (since wait4dar is off). DAR is applied only
during dither or nod. Helps acquiring the star faster,
no overhead, DLM's favorite!

option fsm:
DAR compensation is sent to the FSM, nothing to the DT ctrl offset.
Dar compensation is sent for each frame. Good for consecutive
long exposures at the same location.

option on :
DAR compensation is applied at all time and offloaded to the
FSM for every frame
