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 ================== 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) = 8.7 Min = 4.8 Max = 14.9 (Baseline Ft-Nt on 1933-400) RMS = 2.2 Total time: 1439 minutes ( 24.0 hours).
