WACO Correlator Report for NA417 (exp# 8417) Obs: 24/25 April 2001 doy 114/115 Correlated: 01 May 2001 - 08 May 2001 Exported: done 91% Qcodes 5-9 6% Qcode 0 2% Qcodes BDEFG Kokee (K): OK manual p-cal Algonquin (G): OK S-band interference in last channel Fortaleza (F): OK NyAlesund (O): OK Gilcreek (A): OK Wettzell (V): OK S-band delay rate residuals show ionospheric disturbance on some baselines 154 scans (26%) reprocessed. We had an SU lose P-cal processing without indication other than in the details box. Reseting the SU fixed the problem. 24 scans were reprocessed as a result. Otherwise, the high reprocess rate was due to no one factor.

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.
