Looks like that  "STOP" in SOP GUI failed , but a few commands (like =
"close" shutter) in "cart change"  were executed successfully even when =
the unstopped exposure was=20
going. =20
Currently, we need the gang connector at dense pack for cart change =
dark, the dark cannot be incorporated into gang change command. But it =
should be able to be
incorporated into instrument change in APOGEE SoP.=20
Looks like that "STOP" on SOP GUI doesn't work, will "ABORT" cleanly =
stop the ongoing science exposure in this case.  It would be nice that =
there is a way to stop or
abort an ongoing exposure, and a command to recover the dither position =
to "A".=20
