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

 1.1 General remarks
 
 a) 2015-04-18T15:08: IMU went on, pointings 22,23,24 missed.
 
 b) 2015-04-19T15:26: IMU on, pointing 44 interrupted, 45 missed.
 
 1.2 Pointings summary

   Remarks: Only Science Windows (ScWs) of type 'pointing' are considered.
 - Exposures info from POD version 4. Pointings info from TSF version 13. 
 - 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.
