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) = 7.6 Min = 1.3 Max = 31.3 (Baseline Hh-Ww on 0405-385) RMS = 5.0 Total time: 1450 minutes ( 24.2 hours).
