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) = 7.5 Min = 0.0 Max = 34.3 (Baseline Kk-Km on 0104-408) RMS = 4.9 Total time: 1436 minutes ( 23.9 hours).
