 Legend:
 QC = 0   Fringes not detected.
    = 1-9 Fringes detected, no error condition. Higher #, better quality.
    = B   Interpolation error in fourfit.
    = D   No data in one or more frequency channels.
    = E   Maximum fringe amplitude at edge of SBD, MBD, or rate window.
    = F   Fork problem in processing.
    = G   Fringe amp in a channel is <.5 times mean amp (only if SNR>20).
    = H   Low Phase-cal amplitude in one or more channels.
    = N   No valid correlator data.
  Tot     Total number of scans in schedule.
  Minus   Scans in original schedule file for which correlation was not
          attempted, usually because of known station problems.
