1. Planning summary
===================
1.1 General remarks
a) 2018-08-18T01:01: Bad frames from KIR caused a series of failures. Pointings 13, 14, 15, 16 17, 18
missed due to command failure and then AIMU on (loss of guide star due to a cluster).
b) 2018-08-18T21:13: PICsIT spurious reset in slew 198900310021.
1.2 Pointings summary
Remarks: Only Science Windows (ScWs) of type 'pointing' are considered.
- Exposures info from POD version 3. Pointings info from TSF version 2.
- 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.
