WACO Correlator Report for NA444 (exp# 8444) Obs: 30,31 Oct. 2001 doy 303/304 Correlated: 9 Nov. 2001 to 14 Nov. 2001 Exported: done 89% Qcodes 5-9 5% Qcode 0 4% Qcodes BDEFG Station notes: Kokee (K): OK manual p-cal. Algonquin (G): OK Intermittant S-band interference in last channel Manual p-cal Formatter sync problems (see clocks) Fortaleza (F): Started late at 303-1909 and ended at 304-0334: mechanical problems Matera (I): Lost 303-2159 -> 2220 : recorder problem Dropped frequency 2322.99 (f): caused G-codes almost 100% of scans. Remaining large number of G-codes due to many S-band channels affected by interferance.

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.
