Schedule ======== This is a new schedule generated by Alan Fey using sked. Correlation =========== Media should be shipped to the correlator as soon after the experiment as practical. Special procedures ================== N/A 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) = 7.4 Min = 0.0 Max = 30.2 (Baseline Km-Nt on 1921-293) RMS = 4.6 Total time: 1437 minutes ( 24.0 hours).
