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

 1.1 General remarks
 
 a) Telemetry gap affected pointings 8, 9, 10.

 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. 
  • Exposure 18320001: '3C 273', 5x5 (27x3400s) 27 pointings: 18320002 -> 18320028, 92224s/91800s (+7m03s) Deviations: 18320008 7234/3400s: see 1.1.a) 18320009 0/3400s: see 1.1.a) 18320010 3218/3400s: see 1.1.a)
  • Exposure 18320002: '3C 273', 5x5 (1x3400s) 1 pointing: 18320029, 3400s/3400s (+0s)
  • Exposure 18320003: '3C 273', 5x5 (25x3400s) 25 pointings: 18320030 -> 18320054, 87494s/85000s (+41m34s)
