MDM Trouble Report for 2011 Jan 5 Telescope: 2.4m Observer(s): Shields (Ohio University) Instrument: OSMOS Problem(s) Encountered: 1) Significant leak has appeared in the dewar hose. 2) Thorstensen's osbias and osctrtask routines fail with new OSMOS data despite still working on older test images with same dimensions. Cause is most likely related to the fact that the fits data header content has changed, with information including overscan and data sections not included. I tried modifying data files with hedit to include overscan and data sections but the routines still didn't work, so this diagnosis is incomplete. ------------------------------ Submitted on 2011 Jan 6 [6:36:40]
