+CORRELATOR_NOTES

 The SR1U fringes were not detected in many scans as follows.
  (263-0744 to 263-0749, 263-0753 to 263-0814 and 263-0819 to 263-0825)
 Channels flagged for fringe fitting.

 Scan 263-0739: FQ = 0 on S-band, source 1842+681
 Scan 263-0754: FQ = 0 on X/S-band, source 0322+222
 Scan 263-0800: FQ = 0 on S-band, source 1842+681
 Scan 263-0819: FQ = 0 on S-band, source 1842+681
 There were good integration time but low SNR.


+STATION_NOTES

 WETTZELL(V-Wz): SR1U pcal amplitudes were weak in many scans.
                 Transfer rate: 440 Mbit/s (Tsunami UDP protocol)

 MK-VLBA (M-Mk): OK.

 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.
