Dan and Rob stayed over thru first part of H33 shift to work issues noted in Dan's M33 shift report. Problem of not finding FID lights in OBSID 1093 was traced to sign error in offline system software which calculates the nominal positions of the FID lights for off-nominal aim points (SIM Z translations away from 4 nominal instrument aim points). Problem documented in E-mail by RAC. Problem of having no images in ACIS-I plate focus series (OBSID's 1270, 467, ...) traced to lack of update to the ODB_SI_ALIGN alignment matrices for ACIS-I (and HRC-I/HRC-S). Plan as documented by Dan in M33 shift report is to run P7 load thru the OBSID 1271 (about 236:1945), then terminate P7. This will produce 5 bad observations (1270, 467, 466, 468 and 1271). Load P7 will be replanned starting with ACIS-I plate focus measurements, with corrected alignment matrices. This P7 replanning will take place early tomorrow morning in time for review and uplink after the 236:1945 AOS. Replacement OBSID's were generated: 1270 --> 1276 467 --> 1277 466 --> 1278 468 --> 1279 1271 --> 1280 EVENTS DONE OBSID -------------- ---- ----- Start Shift 236:0200 1270 ----- Real time------ Running OBSID 1270 at start of shift ongo (SIM TT = 92905, SIM FA = -167) ACIS stop science for 1270 236:0315 Start maneuver to next target 236:0315 Move SIM FA to -336 steps 236:0316 Change OBSID to 467 236:0318 467 ACIS start science for 467 236:0330 ACIS stop science for 467 236:0451 LOS Madrid 236:0545 ----- Out of Contact------ Shut off ACIS VID boards for rad entry 236:0550 Enter Radiation zone 236:0550 AOS Goldstone (DSS 27) 236:0640 ----- Real time------ Start SSR dump End SSR dump 236:0902 LOS Goldstone 236:0920 ----- Out of Contact------ Perigee 236:1017 End shift 236:1000 NOTES/ISSUES/PROBLEMS --------------------- See above. 1) List of OBSID's is kept at: /data/mpcrit1/oac/obsids-for-oac.list
