--------------------------------

14:15 : Started observation with TGC. 
14:50 : Noticed that channel width for GWB is less than expected.
15:00 : Restarted observation with ONLINE. As TGC was giving issues for GSB, GSB was not halting.
------------------------------------------------------------------------
16:00 : C08 and W04 released for observation.
19:48 : Stopped command file.
19:50 : Started scan on 3C48.
20:00 : Stopped scan observation session over.
