+CORRELATOR_NOTES

 The SR1U fringes were not detected some scans.

 Scan 340-0730: FQ = 0 on X/S-band, source 0748+126
 Scan 340-0736: FQ = 0 on X/S-band, source 1053+704
 Scan 340-0754: FQ = 0 on X-band, source 0827+243
 Scan 340-0801: FQ = 0 on X-band, source 1053+704
 Scan 340-0816: FQ = 0 on X-band, source 0641+392
 Scan 340-0820: FQ = 0 on S-band, source 0827+243
 There were good integration time but low SNR.

    = D   : No data in one or more frequency channels.
    = G   : Fringe amp in a channel is <.5 times mean amp (only if SNR>20).
