Schedule ======== This is a new schedule generated by Dirk Behrend using input from Alan Fey using sked. Correlation =========== This experiment will be correlated at the WACO Correlator. Data 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.
