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.
