Resyncs follow tape stoppages and formatter reconfigures. For VLBA stations, total reconfigures and reconfigures during recording are shown. Reconfigures during recording can cause slow correlator sync. Any reconfigure can slow sync at JIVE.

The solar corona can cause unstable phases for sources too close to the Sun. 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) J0423-01 92.5 0827+243 32.7 OJ287 26.0 3C279 38.8 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. For common VLBI bands, this is: 327 MHz 117. deg 610 MHz 81. deg 1.6 GHz 45. deg 2.3 GHz 36. deg 5.0 GHz 23. deg 8.4 GHz 17. deg 15.0 GHz 12. deg 22.0 GHz 9. deg 43.0 GHz 6. deg Source separations in degrees for pairs closer than 30.00 degrees. 0827+243 OJ287 6.8791 J2000 coordinates formatted for possible transfer to the correlator data base: name = 'J0423-01' ra = 04h23m15.800727s dec = -01d20'33.06538" name = '0827+243' ra = 08h30m52.086189s dec = 24d10'59.82040" name = 'OJ287' ra = 08h54m48.874929s dec = 20d06'30.64085" name = '3C279' ra = 12h56m11.166557s dec = -05d47'21.52467" Catalogs: Station: /home/filehost/cwalker/sched/catalogs/stations.dat Version: 2005Jul29-10:17:42 Location: /home/filehost/cwalker/sched/catalogs/locations.dat Version: 08 Mar 2005 Frequency: /home/filehost/cwalker/sched/catalogs/freq.dat Version: 2005Jul29-10:17:42 Source: /home/filehost/cwalker/sched/catalogs/sources.vlba Version: 2005 March 1 Code versions: Release version: 6.02 July 2005 Version of VEX standard: 1.50 Version of VEX code: 0.85 Version of plot code: 1.05 Version of ephemeris code: 1.01 Version of PGPLOT: v5.2.0
