The second is 1 hour of single band dual pol X band. It is expected stations will require ~ 1 hour to change receivers between the tests. The schedule consists of long integrations on strong calibrators: Ftp-fringe tests are scheduled ~ every twenty minutes throughout the experiment: 12:10:00 scan 2 J1848+3219 12:30:00 scan 4 J1848+3219 12:50:00 scan 6 J1848+3219 Gap for setup change 13:30:00 scan 8 J1848+3219 13:50:00 scan 10 J1848+3219 14:10:00 scan 12 J1848+3219 14:30:00 scan 14 J1848+3219 14:50:00 scan 16 J1848+3219 Clear skies!
