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) = 10.6 Min = 0.0 Max = 51.4 (Baseline Kg-Nt on 0834-201) RMS = 6.4 Total time: 1447 minutes ( 24.1 hours).
