ACIS SOT shift report See http://cxc.harvard.edu/mta/SOT_reports/sot-shift.html Shift M7155. Start at 2019:054:02:20 GMT 9:20pm February 22, 2019 ACIS Personnel: Paul Plucinsky at the Hampshire St. OCC John ZuHone, Ken Gage, Dick Edgar, Gregg Germain on the TIF PLAN: ----- 1. Verify proper configuration for OBSID 22110, the second Sco X-1 observation 2. Execute CAP 1482 to change the OBSID, activate SCS135 to stop the Science Run, load CC_00082, and start a new science run NOTES/ISSUES/PROBLEMS --------------------- No problems. ACIS is now running with SIMODE CC_0082, the 6 ACIS-S array CCDs are on. Count rates are high on S0, S1, S2, S4, & S5 so we know the dispersed spectrum is on those CCDs. SUMMARY: --------- CAP1482 ran as expected.
