General strategy: Alternate between target MG0414 and "phase-ref" J0422+0219 with a ~10-15 min cycle. This is no full phase-referencing. Once an hour observe one of the bright fringe-finders/calibrators 3C84, 0528+134, DA193. Scans are split into two with a gap between them. Gaps are 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. (Once we only use VLBA, we keep some gaps for disk changes, now at the beginning of scans. They partly overlap with slewing times.) Special strategy for the 2.5h with Arecibo: Start with 0234+285 as fringe-finder. Then alternate between MG0414 and alternative phase-ref J0409+0640 (closer to target but weaker). At the end (when MG0414 is not accessible from Arecibo anymore), go to 0528+134. For Effelsberg there are >=8min recording gaps that should be used for pointing checks: 22 47 20 - 22 55 20 before MG0414 01 47 20 - 01 55 20 before MG0414 03 47 20 - 03 55 20 before MG0414 07 25 20 - 07 49 00 before 0528+134 (implicit autodown gap) 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 140.6 0234+285 156.4 3C84 141.2 J0409+0640 142.0 J0422+0219 138.0 0528+134 122.6 DA193 115.7 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
