+CORRELATOR_NOTES
Scan at 341-0814, and 341-0829 were not correlated !!
341-0814: failed fringe fitting in our program.
341-0829: failed to load data (MK-VLBA) in our program.
Scan 341-0809: FQ = 0 on X/S-band, source 0920+390
Scan 341-0812: FQ = 0 on X/S-band, source OJ287
Scan 341-0824: FQ = 0 on X/S-band, source 0955+476
There were good integration time but low SNR.

Legend:
QC = 0 : Fringes not detected.
= 1-9 : Fringes detected. no error condition. Higher #, better quality.
= D : No data in one or more frequency channels.
= G : Fringe amp in a channel is <.5 times mean amp (only if SNR>20).
= N : No valid correlator data.
= - : Not scanned.
= Tot : Total number of scans in schedule.
