Recording to ATNF V005B
Began recording at UT 04:02
Did not get time to run fringe check schedule.
No fringes confirmed on first source of main experiment.
UT 05:09: DAS profile changed to 64MHZ_F.PRO as part of attempt to diagnose lack of fringes. (Should be identical to 64MHZ_N.PRO)
Fringes confirmed at UT 05:54. Likely that data has been good from the beginning of the run. Reason for earlier lack of fringes unknown.
