+CORRELATOR_NOTES

 The UT1 could not be estimated because there were few scans that 
 could detect fringes. Therefore, we will not submit the vgosDB.


+STATION_NOTES

 WETTZELL(V-Wz): OK.
                 Transfer rate: 430 Mbit/s (Tsunami UDP protocol)

 MK-VLBA (M-Mk): 45 of 60 minutes of data was lost due to Vdif_OS_diff failure.

 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.
    = Tot : Total number of scans in schedule.
