-----------------------------------------------------------------------
15:00:00 : Started set-up in GWB mode only due to space problem in gsb.
15:28:31 : Started scan on 3C48 for ~ 4.83183 min.
15:35:12 : Started scan on 3C48 for ~ 3.57914 min.
As Phase cal 3C119 was not risen hence taken data on target pulsar after phasing on 3C48. 
15:42:09 : Started scan on B0355+54 for ~ 19.6852 min.
-----------------------------------------------------------------------
16:03:00 : GSB space problem solved, so started observation in both gsb and gwb mode.Restarted GWB. Power equalized in GSB.
-----------------------------------------------------------------------
16:15 : As C02 released for observation hence set up done to C02 and added in GAC.
16:19:32 : Started  command file.
 '/odisk/gtac/cmd/35_031/13jan2019.cmd'
03:02 : Closed observation session after taking phasing scan on phase cal.
