COVER LETTER: Target: PGC032873 Primary phase-reference calibrator: J1058+4304 Secondary phase-reference calibrator: J1058+4248 (10:58:00.753096, +42:48:44.15638, J2000) Fringe-finder: 4C39.25 Calibrator for e-MERLIN: 3C286 Note: Here is another candidate of the secondary p-ref calibrator: J1059+4051 (10:59:51.90608208, +40:51:14.1996044, J2000) This candidate is farther from the target but relatively compact. I am unsure which one is better. These two secondary p-ref calibrators are not included in the catalogues. Add manually.
