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.

Observation date used in B1950/J2000 coordinate conversion (PRECDATE): 1979.900 No adjustments are made for rates (DRA, DDEC). Scan hours are for recording scans only. Baseline hours are only counted for scans above horizon at both ends.

SCHED provides warnings at individual scans for distances less than 10 degrees. The distance from the Sun to each source in this schedule is: Source Sun distance (deg) J1826+18 111.6 J2136+00 71.8 OQ208 137.2 3C279 157.2 J1310+32 130.4 Barry Clark estimates from predictions by Ketan Desai of IPM scattering sizes that the Sun will cause amplitude reductions on the longest VLBA baselines at a solar distance of 60deg F^(-0.6) where F is in GHz.
