'/odisk/gtac/cmd/ruta/33_030/33_030_16-17nov_cmd' Note : Scan No. 8 having less record.Because of online problem, stopped scan on target before 3-4 min. 21:05 : C14 ABC time out. Note : scan No 10 and 11 are bad because of wrong tpa value in GSB only not in GWB. 23:45 : Stopped command file and started scan on phase cal for 5 mins. 00:20 : Observed 10 mins each for 3C48 and 3C147. 00:20 : Closed observation session.
