+CORRELATOR_NOTES

 Scan 355-0816: FQ = 0 on X/S-band, source 1030+415
 There was good integration time but low SNR.



+STATION_NOTES

 WETTZELL(V-Wz): The SR1U fringes in the following scans were not detected due to RFI.
                 (8 scans from 355-0807 to 355-0816)
                 Transfer rate: 400 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.
