 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.
