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

 1.1 General remarks
 
 a) Maintenance gap at ISDC: Pointings 10 to 14 missed (will be recovered in cons)

 b) Preprocessing restarted due to a loss of synchronization. Unfortunately, Pointings 16 to 19 failed,
    but they will be recovered in consolidated)

 c) Pointing 19 missed (no record in AHF)

 d) Pointing 39 missed

 e) 2019-12-04T18:42: VDM5V ISGRI anomaly. Patch performed by MOC at 20:41.
 
 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.
