 1. Planning summary
 ===================

 1.1 General remarks
 
 a) 2022-08-26T07:30: Pointing 42 missed.

 1.2 Pointings summary

   Remarks: Exposure info from POD. Pointing info from TSF. 
 - Durations in exec/planned format; data gaps and bad time intervals not excluded from total time.
 - Deviations: only unexpected deviations >30 secs for pointings assigned to an exposure reported;
   expected deviations (first & last pointings of an exposure longer than planned) not reported. 
  • Exposure 25410001: 'SAX J1808.4-3658', hexagon (28x3470s) 28 pointings: 25410004 -> 25410031, 96932s/97160s (-3m48s)
  • Exposure 25410002: 'SAX J1808.4-3658', hexagon (24x3470s) 24 pointings: 25410032 -> 25410055, 84502s/83280s (+20m21s) Deviations: 25410042 44/3470s: see 1.1.a)

2. NRT Data processing ====================== 2.1 Telemetry * TM gaps of more than 30 seconds: 2022-08-25T21:17:57 2022-08-25T21:18:28 * Frames missed: - * Statistics: Mean Rate: 15.99 frames/sec (mean) Frames: 3427403 total : 0 missed : 2589520 TM : 837883 idle : 0 invalid Packets: 5194495 total : 1891 missed : 5179040 TM : 0 tcmd : 15455 time : 0 idle : 0 invalid * No error 2.2 Auxiliary files OLF: 63 ASF: 61 THF: 61 2.3 Pre-processing / OPUS pipelines Nothing special * No error 2.4 ISGRI context table 2022-08-26T16:39: IIMG_SDCMOC_D20220824173143_00001.INT 2022-08-26T18:31: IIMG_SDCMOC_D20220824173143_00002.INT 2nd version provided by IRFU/SAp, Saclay (F) 3. Alerts ========= 3.1 All alerts except OOLs and missing scientific data * Level 2: 603 The pointing hasn't increased by one. From 41 to 43 (2541_0001_AHF) -> see 1.1.a) * Level 1: 604 Exposure time is 44 sec. instead of 3470 sec. Pointing ID (BCPPID): 25410042 -> see 1.1.a) 3.2 Parameter out of limits IBIS: ----- Due to Solar minimum, the IBIS veto limits are not appropriate resulting in too many alerts ScWs: 254100040010 - 254100550010 V1S_MBOT_MCOUNT V1S_MLAT_MCOUNT ScWs: 254100040010 - 254100550010 IOE_MDOS_MMCE4,6 3.3 Missing scientific data (taken from alert 3050) IBIS: ----- ScW: 254100410010 These data structures are missing: PICS-SIMH-RAW (or ALL) for mode Observation standard (41) PICS-SISH-RAW (or ALL) for mode Observation standard (41) OMC: ---- ScW: 254100420010 These data structures are missing: OMC.-SHOT-RAW (or ALL) for mode Science Normal (42) 4.
