eBOSS don=E2=80=99t request any post-cals, please ignore SoS warning on =
post-cals.=20
eBOSS team, if this has be changed, please let us know.
However, we need to take post-cals for MaNGA if an observation on a =
MaNGA=20
plate is over 1 hour (DOS should give post-cals reminder).=20

Because it is a APOGEE-lead plate, SoP loads a co-observing GUI although =
MaNGA=20
holes are not plugged.  Petunia does show which co-observing plates are =
actually have both survey
fibers plugged, observers could mis-read one row. So it=E2=80=99s better =
to have a SOP GUI of pure APOGEE=20
plate since we do have all information in plateDB.=20
This problem resulted 45 minutes time loss (the first gotoField issued =
at ~8:56 Z, and the last one
at ~9:41Z).  There was also a fiducial error involved in one slew. =
Observers ended the night observation
at 8 degree morning twilight when the scheduled ending time is 12 =
degree, which got 20 minutes on-sky time
back, reduced the time loss to 25 minutes.=20
DanO: For the time tracking, please attribute 5 minutes to softwares, 5 =
minutes to hardwares (correct the=20
fiducial and re-slew), and 15 minutes to operational error.=20
