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

 1.1 General remarks

 a) 2017-07-25T07:40: SPI annealing #29, start of outgassing of coldbox.

 b) 2017-07-27T03:09: SPI DPE reset during SPI annealing

 c) 2017-07-27T03:09: "ACC AIMU ON", pointing 7 missed (not in AHF).

 c) 2017-07-27T03:09: SPI DPE reset during SPI annealing.

 1.2 Pointings summary

   Remarks: Only Science Windows (ScWs) of type 'pointing' are considered.
 - Exposures info from POD version 1. Pointings info from TSF version 1. 
 - 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 18430001: 'Cygnus X-1', staring (1x85583s) 1 pointing: 18430004, 85696s/85583s (+1m53s)
  • Exposure 18430002: 'Cygnus X-1', staring (1x4417s) 1 pointing: 18430005, 4411s/4417s (-5s)
  • Exposure 18430003: 'SPIBIS Cygnus X-1', staring (1x87005s) 1 pointing: 18430007, 76425s/87005s (-2h56m19s) Deviations: 18430007 76425/87005s: see 1.1.a)
