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.
