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

 1.1 General remarks
 
 a) 2021-10-20T03:15: Pointing 02 missed.

 b) 2021-10-20T04:07: Pointing 04 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.
