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) = 8.6 Min = 1.2 Max = 32.0 (Baseline Hh-Ke on 0920-397) RMS = 5.8 Total time: 1439 minutes ( 24.0 hours).
