Problem Reports
PR NumberTimesTime LostDescriptionResponse
435207:12-07:1600:04On ACQ cam set analysis region with old fiducial outside of box. Set the guide box. Started the loop and activated the loop, and even though fiducial was outside of analysis region the telescope made offset according to fiducial. Sent us into uncharted territory with desired object outside of guide probe view. We could not recover and had to abort trajectory and test.
435307:32-07:3200:00Guiding on ACAM just stopped working. We were guiding on ACQ cam while taking images in guide probes, and even though the object was in the analysis region and being recognized with a centroid marker, no corrections were being made.
430008:00-08:0300:03Could not manually load next target in TCS. tcs_server uses 100% CPU. Ctrl-c termination leaves tcs_server.conf running, no indication of defunct-ness. Killed everything, restarted.
435406:05-06:0800:03CWFS device offline error when trying to set exposure time. Could not do anything in CWFS camera window. PAS appeared to be behaving normally otherwise.Killed and restarted just PAS and it worked fine without aborting track, etc.
435505:00-05:0000:00Frequent HFC faults after hitting the Abort Tracker button.
435601:30-01:3000:00Could not adjust HEFI light source voltage; upper limit set at 6 in software. Wanted to increase voltage to try to get better IOF and OOF images at end of stack measurements.
435708:50-08:5200:02HFC fault while moving to star trajectory.
