To:sot_shift from: Dan Schwartz date: 15 Jan 10, 10:00 EST Subject: SOT shift report 2010-01-15 L3830 -------- See http://asc.harvard.edu/acis/SOT_reports/sot-shift.html, or /proj/web-cxc/htdocs/acis/SOT_reports/Jan_15_2010_L3830.txt. Shift L3830. Start at 015:13:00 GMT = 08:00am 15 Jan EST End 10:00am 15 Jan SOT Lead DAS (Times will be given in GMT on day 015.) PLAN ---- Continue running load JAN1110A. Go through perigee passage, performing the quarterly ACA dark current calibration. Upon egress do obsid 11271, an ACIS-S observation of the blue compact dwarf galaxy DDO 68, to study the ratio of X-ray luminosity to star formation rate, to determine if it differs from normal galaxies. Then do obsid 11301, an ACIS-S observation of the Extremely Metal Poor Galaxy KUG 0937+298, as part of a survey to test if Ultra-Luminous X-ray sources prefer metal poor galaxies as is predicted. NOTES/ISSUES/PROBLEMS --------------------- From the 9am status meeting: Three comms over the past day. No issues. JAN1810A loads were approved yesterday. Quarterly dark current calibration will be performed during the ~8 hour comm beginning this afternoon. NOTE: dither is disabled during dark current cal.
