Higher number = 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). = 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.
