SUMMARY: ---------- The DEA-A turned on nominally. ACIS behaved as expected when commanded to execute a science run. We have to conclude that this was another example of a "spurious" command to or within the ACIS PSMC. All is well. 1) Detailed Timeline GMT 259:16:50 AOS on DSS 66 259:17:02 OC/CC complete the SSR dump OC/CC start uplinking the loads in step 1 of the CAP 259:17:21 all loads uplinked, including the deadman 259:17:22 Enable and activate SCS 239, the deadman load 259:17:22 send a stopScience command to ACIS, nominal receipt 259:17:25 change OBSID to 62825 259:17:26 verify TLM FMT 2 259:17:27 send WSPOW00000 command to ACIS in step 6, nominal receipt, ACIS notices DPA input voltages dropping 259:17:29 ready for the crucial step 7 of the CAP to turn on the DEA A side A 259:17:30 DEA A turns on nominally, all voltages and currents nominal Yeah !!! 259:17:32 send command to power up the S0 video board, TLM looks nominal 259:17:34 All TLM from the power-on looks good so we decide to start a CTI measurement 259:17:35 start commanding for a nominal CTI measurement 259:17:40 startScience command for the CTI measurement TLM looks nominal 259:17:55 first bias data 259:18:05 bias data complete 259:18:06 first event data, event rates look reasonable 259:18:20 ACIS has seen enough TLM that the OC/CC can go ahead and clear/disable the SCS slots including the deadman load 259:18:40 end of activity 2) Chandra state at the middle of the Pass UTC 2005:259:16:52:02 (Sep16) f_ACE 4.47e+03 F_CRM 6.95e+08 Kp 3.0 R km 105742D OBT 2005:259:16:51:41 CTUVCDU 15941598 OBC s/w NRML FMT2_NORM CPEstat NORM OBT 243276701.37 ONLVCDU 15941584 OBC Errs 0 OBSID 5787 EPState SUN SIM TTpos 75624 HETG Angle 79.09 PCADMODE NPNT RA 36.034 Bus V 29.77 SIM FApos -467 LETG Angle 77.59 PCONTROL NPNT Dec -4.225 Bus I 28.24 AOFSTAR GUID Roll 90.002 ACA Object FFFSSSSS Dither ENAB HRC-I HV OFF ACA ImFunc TTTTTTTT Dith Yang 6.92 Yaw Rate 0.05 HRC-S HV ON ACA CCD Temp -15.6 Dith Zang 4.21 Pitch Rate 0.11 OBSMode NEXT ACA Int Time 1.698 Roll Rate -0.02 Door OP UNAC AOACSTAT OK FSS SunBeta SUN Door CL UNAC FSS Alfa -1.40 Batt 1 SOC 100.00% Avg HRMA Temp 70.61 FSS Beta -48.60 Batt 2 SOC 100.00% ACIS Stat7-0 67 Avg OBA Temp 52.65 SA Resolv 138.43 Batt 3 SOC 100.00% Cold Rad -127.9 OBA Tavg Fault NFLT SA Sun Pres ILLM Warm Rad -82.0 OBA Trng Fault NFLT +Y SA Amps 13.91 RadMon ENAB HRMA power 65.70 SCS 128 ACT -Y SA Amps 13.91 EPHIN Geom LARG OBA power 73.70 SCS 129 ACT +Y SA Temp 113.28 E150 1463.4 SCS 130 ACT -Y SA Temp 114.51 E300 37.7 Roll Mom. 3.251 SCS 107 INAC E1300 1.2 Pitch Mom. -7.176 UpL Cmd Acc 15469 EPH A-Leak 1.0200 P4GM 31.4 Yaw Mom. 0.644 Cmd Rej A 163 EPH B-Leak 0.6880 P41GM 0.2 3) Chandra state at the end of the Pass UTC 2005:259:18:31:01 (Sep16) f_ACE 3.14e+03 F_CRM 7.93e+08 Kp 4.0 R km 100633D OBT 2005:259:18:30:43 CTUVCDU 15964786 OBC s/w NRML FMT2_NORM CPEstat NORM OBT 243282643.28 ONLVCDU 15964776 OBC Errs 0 OBSID 62825 EPState SUN SIM TTpos 75624 HETG Angle 79.09 PCADMODE NPNT RA 36.033 Bus V 29.61 SIM FApos -467 LETG Angle 77.59 PCONTROL NPNT Dec -4.226 Bus I 31.02 AOFSTAR GUID Roll 90.002 ACA Object FFFSSSSS Dither ENAB HRC-I HV OFF ACA ImFunc TTTTTTTT Dith Yang 4.80 Yaw Rate 0.43 HRC-S HV ON ACA CCD Temp -15.6 Dith Zang 1.12 Pitch Rate 0.07 OBSMode NEXT ACA Int Time 1.698 Roll Rate -0.18 Door OP UNAC AOACSTAT OK FSS SunBeta SUN Door CL UNAC FSS Alfa -1.45 Batt 1 SOC 100.00% Avg HRMA Temp 70.58 FSS Beta -48.66 Batt 2 SOC 100.00% ACIS Stat7-0 64 Avg OBA Temp 52.57 SA Resolv 138.43 Batt 3 SOC 100.00% Cold Rad -127.9 OBA Tavg Fault NFLT SA Sun Pres ILLM Warm Rad -82.0 OBA Trng Fault NFLT +Y SA Amps 15.46 RadMon ENAB HRMA power 94.40 SCS 128 ACT -Y SA Amps 15.46 EPHIN Geom SMAL OBA power 78.30 SCS 129 ACT +Y SA Temp 112.66 E150 3524.4 SCS 130 ACT -Y SA Temp 113.89 E300 66.9 Roll Mom. 3.408 SCS 107 INAC E1300 3.9 Pitch Mom. -7.771 UpL Cmd Acc 15841 EPH A-Leak 1.0200 P4GM 9.8 Yaw Mom. 0.890 Cmd Rej A 207 EPH B-Leak 1.0200 P41GM 0.0
