+CORRELATOR_NOTES

 The SR1U fringes were not detected some scans.

 Scan 030-0730: FQ = 0 on X-band, source 1059+282
 Scan 030-0754: FQ = 0 on X-band, source 1059+282
 There were good integration time but low SNR.


+STATION_NOTES

 WETTZELL(V-Wz): The SR1U fringes in following scans were not detected by RFI.
                 (18 scans from 030-0744 to 030-0803)
                 Transfer rate: 360 Mbit/s (Tsunami UDP protocol)

 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.
