J0414+0534 (512 Mb/s) Notes: COVER LETTER: GW019A MG J0414+0534 at 18cm, EVN+VLBA+VLA27+Arecibo 07 June 2008 05:00 - 24:00 UT 05:00 - 10:00 EVN only 10:00 - 13:00 EVN + VLBA 13:00 - 14:30 EVN + VLBA + VLA27 14:30 - 17:00 EVN + VLBA + VLA27 + Arecibo 17:00 - 24:00 VLBA + VLA27 ( vla has own schedule (3C286) for the last 10 min ) sources: -------- MG0414 target gravitational lens = J0414+0534 own position between the four images from the VLBA calibrator survey: http://www.vlba.nrao.edu/astro/calib/ J0412+0438 = 0409+045 compact phase-ref 0.16Jy at 1.07deg distance alternative "phase-ref" source for Arecibo bit J0422+0219 = 0420+022 compact phase-ref 1.02Jy at 3.85deg distance standard "phase-ref" source J0409+1217 = 0406+121 compact phase-ref 1.02Jy at 6.84deg distance good fringe-finder for Arecibo before MG0414 from the VLBA fringe-finder surcey: http://www.aoc.nrao.edu/~analysts/vlba/ffs.html 3C84 = J0319+4130 strong on short baselines, unpolarised 0528+134 = J0530+1331 good fringe-finder, close to sun good for Arecibo after MG0414 DA193 = J0555+3948 good fringe-finder, also for D-terms, maybe even polarisation p.a. 3C286 for VLA only to calibrate absolute flux and maybe pol. p.a. General strategy: Alternate between target MG0414 and "phase-ref" J0422+0219 with a ~15 min cycle. This is no full phase-referencing. Once an hour observe one of the bright fringe-finders/calibrators 3C84, 0528+134, DA193. Longer scans (target and fringe-finder sources) are split into two with a gap between them. Shorter scans (phase-ref) have the gap at the end with a minimum-duration (15sec) dummy scan afterwards. Gaps are mostly 20sec. According to SCHED, Hh does not reach the source within 20sec, but since there are no slews at the gaps, this is not a problem. The SCHED warning about TSYS measurements not being on source for Hh can be ignored. We do not use gaps at the beginning of scans in order to avoid having to wait for the slowest station before TSYS can be measured. No gaps after 17:00 when we only have VLBA and VLA27. Special strategy for the 2.5h with Arecibo: Start with J0409+1217 as "fringe-finder". Then alternate between MG0414 and alternative phase-ref J0412+0438 (closer to target but weaker). At the end (when MG0414 is not accessible from Arecibo anymore), go to 0528+134. Thanks!

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) MG0414 20.9 3C84 28.7 J0409+1217 16.7 J0412+0438 22.0 J0422+0219 22.8 0528+134 11.3 DA193 20.2 3C286 106.2 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
