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) = 12.1 Min = 8.2 Max = 18.7 (Baseline Hh-Ho on 0629-418) RMS = 2.8 Total time: 1442 minutes ( 24.0 hours).
