--------------------------------
04:00 : Started set up.
04:19 : Started scan on 3C147 for 8 min.
04:27 : Stopped scan.
NOTE : GWB Acq killed hence restarted command file.
04:43 : Restarted command file from flux calibrator 3C147.
NOTE : The source for Scan no 4 ie. (0842185 ) was transiting hence taken for 4 min instead of 5 min.
08:30 : Dropped source J11162200 as it was transiting and needed too much time to slew between 1120143 also, continued with next sources.
09:15 : Stopped command file.
09:19 : Started scan on 3C286 for 8 mins.
09:25 : Closed observation session.
