Resyncs follow tape stoppages and formatter reconfigures. For VLBA DAR stations, total reconfigures and reconfigures during recording are shown. Reconfigures during recording can cause slow correlator sync. Any reconfigure can slow sync at JIVE. Tapes started before scan start time 236 times. See PRESTART and MINPAUSE. They may have been kept running through short scan gaps. The number can be large because each station/scan combination counts.
