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

 1.1 General remarks
 
 a) Crab observation

 b) 2017-08-29T04:43: IREM crash followed by an IREM clock reset detected. 

 c) Pointing 14 missed
 
 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 18560001: 'Crab', 5x5 (9x3600s) 9 pointings: 18560004 -> 18560012, 32436s/32400s (+36s)
  • Exposure 18560002: 'Crab', 5x5 (6x3600s) 6 pointings: 18560013 -> 18560018, 22784s/21600s (+19m43s) Deviations: 18560014 1752/3600s: pointing 14 missed
  • Exposure 18560003: 'Crab', 5x5 (9x3600s) 9 pointings: 18560019 -> 18560027, 35143s/32400s (+45m43s)

  • Exposure 18560005: 'Crab', staring (1x10000s) 1 pointing: 18560030, 10000s/10000s (+0s)
  • Exposure 18560006: 'Crab', 5x5 (25x2960s) 25 pointings: 18560032 -> 18560056, 74660s/74000s (+11m00s)
  • Pointings with no assigned Exposure 6 pointings: 18560001, 0002, 0003, 0029, 0031, 0057, 4392s/3110s (+21m22s)
