Notes from the correlator: 
Scan 100-0730: FQ = 0 on X/S-band, source 1606+106  Scan 100-0736: FQ = 0 on X/S-band, source 1849+670  
Scan 100-0758: FQ = 0 on X/S-band, source 1746+470  Scan 100-0824: FQ = 0 on X/S-band, source 1806+456  
There were good integration time but low SNR.

Scan 100-0809: FQ = 0 on X-band, source 1053+704  There was 50% or less of assumption file sizes.
