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) = 6.4 Min = 2.0 Max = 25.2 (Baseline Hh-Ww on 1144-379) RMS = 3.9 Total time: 1436 minutes ( 23.9 hours).
