Schedule ======== This is a new schedule generated by Alan Fey using sked. Correlation =========== This experiment will be correlated at the WACO Correlator. Tapes should be shipped to Washington, DC as soon after the experiment as practical. Special procedures ================== None. Summary ======= The following listing is a summary of the observations in this schedule. Average number of obs. per baseline per source(normalized by up-time) = 12.7 Min = 0.0 Max = 24.2 (Baseline Ho-Kk on 1243-072) RMS = 4.8 Total time: 1446 minutes ( 24.1 hours).
