+CORRELATOR_NOTES

 The offset of 1 second was added to carry out the fringe search.

 Scan 052-0741: FQ = 0 on X/S-band, source 1324+224
 Scan 052-0801: FQ = 0 on X-band, source 1418+546
 Scan 052-0804: FQ = 0 on S-band, source 1417+385
 There were good integration time but low SNR.

 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.
