 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.
