! Sample file for LST scheduling. ! File converted to the RDBE on March 17, 2014. Actually just ! changing the station and freq catalogs to the RDBE versions was ! all that was needed. But also take the opportunity to convert ! to DWELL scheduling. ! It also demonstrates phase referencing. ! ! This is the sort of file needed for dynamic scheduling projects ! on the VLBA. ! ================================================================ ! Preferred Dynamic Constraints.
