To:sot_shift from: Dan Schwartz date: 16 Feb 00 , 12:00noon EST Subject: SOT shift report, Shift L208 -------- See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/ascwww/AXAF/extra/science/htdocs/acis/SOT_reports/Feb_16_2000_L208.txt. Shift L208. Start at 047:13:00 GMT = 08:00am 16 Feb EST End 12:00 noon 16 Feb SOT Lead DAS (Times will be given in GMT on day 047. In general times are rough, not precise.) PLAN Continue running load FEB1300c. Finish HRC-I calibration observation of G21.5-0.9 (OBSID 142) then do 3 HRC-S imaging calibrations of that supernova remnant, one on each plate (OBSIDs 154, 150, 146). Do an ACIS-S image of NGC 4569 (OBSID 405), before safing for radiation belt passage and doing the associated CTI measurements. Next Comms: 047:22:45 to 00:25 048:06:32 to 09:50 048:14:15 to 15:15 049:00:40 to 02:00 049:10:30 to 12:00 049:20:00 to 21:30 EVENTS Status at LOS, 047:13:44, was as follows: [SEE NOTE BELOW] PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 4 FIDS = 3 RA = 278.401 deg DEC = -10.591 deg ROLL = 82.445 deg Format = 1 OBSID = 142 (G21.5-0.9, calibration) SIM FA = -715 SIM TSC = -50504 (HRC-I) HETG = OUT (80.6 deg) LETG = OUT (79.1 deg) HRC-S HV is ON EPHIN: A-Leak = 0.2600 mu-a B-Leak = 0.0440 mu-a Descending through 139839 km NOTES/ISSUES/PROBLEMS The CHandra Snapshot is showing 0 for the OBSIDs, and not reporting the telemetry format. This must be a problem with the snapshot, as GRETA reports the expected values. Notes from 9am status meeting. Products for the ACA dark current measurement are to be finalized today. Eric Martin is coordinating with Rob and Tom. He will write a CAP which just says to run the dark measurement procedure. This is planned to run early tomorrow am (1:30 EST) during the long comm pass. Guide/Acquisition star selection meetings start today at 1pm, with Q/A session with Marilyn on how the OFLS works. Kevin is considering 1pm on Friday to reschedule the meeting on defining the instrument operating procedures relative to the maneuvers. CXC archive is updated, so quick look data is flowing again: Evaluation of QL data The following observations from the last ten days should be available for review. If there is no comment after the entry, it means the image has not yet appeared in the book.
