SOURCE SCAN SUMMARY FOR SOURCES LISTED ABOVE Scan hours are for recording scans only. Baseline hours are only counted for scans above horizon at both ends. 'Core' scans are those for which PREEMPT is not 'EXTRA'. The 'DOSCANS' columns are for scans in the range selected by DOSCANS Those are the scans sent to the Vex and other files Source Setup file Frequency sets Core scans (Hours) DOSCANS (duplicates not shown) Scan Baseline Scan Baseline 3C318 sess117.L2048glob 12 18 0.350 0.917 0.433 0.917 ARP220 sess117.L2048glob 1 2 3 4 5 6 7 8 11 12 18 23 8.331 866.845 9.606 914.411 3C286 sess117.L2048glob 18 0.083 0.000 0.083 0.000 J1516+1932 sess117.L2048glob 1 2 3 4 5 6 7 8 11 12 18 23 0.367 34.836 0.433 36.969 J1532+2344 sess117.L2048glob 1 2 3 4 5 6 7 8 11 12 18 23 2.467 256.869 2.917 272.768 EFFECT OF SOLAR CORONA 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) 3C318 111.1 ARP220 107.8 3C286 134.1 J1516+1932 111.9 J1532+2344 108.3 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.
