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) = 7.3 Min = 1.6 Max = 23.0 (Baseline Ho-Sy on 2131-021) RMS = 3.5 Total time: 1446 minutes ( 24.1 hours).
