Modifications Needed to Make this a General User Mode

DARKTIME = 4425.689 / CCD dark time (sec)
NSUBEXPS = 2 / Number of subexposures
OBJT0001 = 'object ' / Pointing type
SEXPOOO1 = 1800. / Object exposure 30x60.0 (sec)
OBJT0002 = 'sky ' / Pointing type
SEXPOOO2 = 1800. / Sky exposure 30x60.0 (sec)
NODPAT = 'bracket ' / Nod pattern for charge shuffling
NODPIX = 700 / Number of pixels to shuffle
NODCOUNT = 30 / Number of full nods per exposure
NODT0001 = 60. / Object exposure per nod (sec)
NODT0002 = 60. / Sky exposure per nod (sec)
INITTIME = 1.593 / software/hardware initialization (sec)
PREPTIME = 7.127 / CCD preparation time (sec)
READTIME = 122.047 / CCD readout time (sec)
TOTTIME = 4556.456 / total time spent in task (sec)

Things to do in the future:

Need a mode in which we do not guide in the off position. Main thing that has to be fixed then is the handshake between the telescope and ICE.
