Added 1041 counts to freq synthesiser to correct maser rate (slow) of 90 nanoseconds per day following cavity tune. Synthesiser adjustment performed at 155/1315 UT. The new value is 55823. The maser now leads GPS by 10.33 microseconds.\\ | Added 1041 counts to freq synthesiser to correct maser rate (slow) of 90 nanoseconds per day following cavity tune.
