MDM Trouble Report for 2015 Mar 23

Telescope: 2.4m
Observer(s): Kay/Moran (Columbia)
Instrument: 4K

Problem(s) Encountered:
When trying to subarray 4K with the scripts (roi1k, roi512), we couldn't take data
with prospero.    An exposure would start, but it would seem to hang, and then
(after a long time) it wold report that the exposure had completed (nothing was
written to disk) and then it would report that the observation had been aborted
(which we hadn't tried to do).  Things worked ok in the larger formats.  But as a
result, we had longer than desired readout times during our frequent focus
checks.  Everything else worked fine.
