Stopped first session and started command next command file. Since phase cal was rising at 11:22 so took 3c48 as flux cal and 3c138 at place of phase cal. 10:07:56 : Started scan on 3C48 for ~ 14.9429 min. 10:25:53 : Started scan on 3C138 for ~ 4.92131 min. 10:33:26 : Started scan on PSZ2G144.83 for ~ 31.4964 min. 11:07:02 : Started scan on PSZ2G144.83 for ~ 20.3116 min. 11:31:06 : Started scan on J0841+708 for ~ 4.92131 min. 11:36:55 : Started scan on PSZ2G144.83 for ~ 51.2711 min. 12:29:06 : Started scan on J0841+708 for ~ 4.92131 min. 12:34:52 : Started scan on PSZ2G144.83 for ~ 51.2711 min. 13:27:01 : Started scan on J0841+708 for ~ 4.92131 min. 13:32:58 : Started scan on PSZ2G144.83 for ~ 51.2711 min. 14:25:08 : Started scan on J0841+708 for ~ 4.92131 min. 14:30:59 : Started scan on PSZ2G144.83 for ~ 13.2428 min. 14:44:56 : Started scan on J0841+708 for ~ 4.92131 min. 14:55:49 : Started scan on 3C48 for ~ 9.21628 min. 15:05 : Closed observation session.
