SHARCS Problem: Long Write To Disk
Problem Description:
Following completion of exposure, sharcs_fe takes an inordinately long time (>30 s) to write fits file to disk.
Manifestation:
Status field in sharcs_fe GUI remains purple for > 30 s (while writing to disk). sharcs_fe may be unresponsive during this time.
Work-around:
-
Attempts to re-start sharcs_fe (sharcs UI) and services
on stealthie.ucolick.org are unsuccessful.
-
In sharcs_fe: Windows...; Window, enter values
of a sub-window (e.g. start x = 915, end x = 1264,
start y = 585, end y = 935).
-
Consequences of windowing:
-
Many of the FITS keywords are not gathered as normal,
which saves time with writing, as well as many fewer
pixels being written to disk. Advise observer to keep
even more careful log than normal.
-
Bias/dark charcteristics of detector vary depending on
windowing. Consequently, bias/dark calibrations may
have to be taken by manually.
Cause:
Unknown. Appears to follow reboot of bigeye.ucolick.org.
