COVER INFORMATION Station: EB_VLBA (Code Eb ) Experiment: Follow-up Imaging of Three NGC4258-like Water Megamasers Exp. Code: BK114C Schedule Version: 1.00 Processed by SCHED version: 6.01 Release: Late March 2005 PI: Paul T. Kondratko Address: Harvard-Smithsonian CfA, MS 10 60 Garden Street Cambridge, MA 02138 USA Phone: 617 497 6996 EMAIL: pkondrat@cfa.harvard.edu Fax: 617 495 7345 Phone during observation: 617 851 3887 Observing mode: 256-4-2 1.3 cm Notes: 10 min setup time. Pointing calibration at the GBT and at EB is crucial and is scheduled every ~1.5 hours. VLA: extend phasing scans on 1434+235 if necessary to obtain reasonable RMS. VLA scan on 3C48 is critical.

The distance from the Sun to each source in this schedule is: Source Sun distance (deg) UGC09618 140.6 0059+581 47.1 0133+476 35.5 0224+671 54.6 0231+1322 5.9 0237+2848 17.4 0238+1636 8.4 0528+134 49.4 0605-085 63.4 0642+449 66.6 0727-115 83.7 0748+126 83.2 0736+017 82.7 0834-201 101.1 0854+2006 96.3 4C39.25 96.7 1124-186 141.0 1357+769 90.4 1606+106 141.9 1611+343 124.2 1637+574 103.2 1655+077 132.9 1741-038 125.8 1749+096 120.0 1920-211 104.7 2145+067 64.0 2223-052 57.9 3C48 21.4 1308+326 132.7 3C286 135.7 1354+195 147.7 1434+235 143.1 J1453+2648 138.7 1502+106 152.7 1641+399 116.1 2251+158 46.9 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.
