I think that the lamp up time is set to 210 sec which is necessary to =
get wavelength
calibration arc lines at the blue end. With the warming up starts before =
=E2=80=9CgotoField=E2=80=9D=20
slews start, and continue to count for during hartmann process. For =
fields
with short slews arc exposures will wait for the warmup time to complete =
while arc=20
exposures will start right after the hartmann for fields with lone =
slews. =20
=46rom time stamps on hartmann and arc exposures of last night,  arc =
exposures
didn=E2=80=99t start right after hartmann for long slews. for some =
fields, the slew and hartmann took=20
5 minutes, but arc exposures still wait another two minutes. Looks like =
that warming
up timer or starting point (not start to count down right after lamps =
are turned on or =E2=80=9Con=E2=80=9D status
are delayed in STUI) get messed up.=20
