COVER INFORMATION Station: EFLSBERG (Code Ef ) Experiment: Characterizing OCRs in dwarf galaxies Exp. Code: ev026b Schedule Version: 2.00 Processed by SCHED version: 11.60 Release 11.6; April 2020 PI: Dany Vohl Address: Anton Pannekoek Institute for Astronomy, University of Amsterdam 1098 XH Amsterdam Amsterdam The Netherlands Phone: +31 6 1887 9982 EMAIL: d.vohl@uva.nl Fax: Phone during observation: +31 6 1887 9982 Observing mode: vlbi Notes: # Please, make sure PHASE CAL is OFF # COVER LETTER: This observation is to observe ILT J015915.79+242500.6 first identified in the LoTSS DR2 data as potential analogue to persistent radio sources associated to some fast radio bursts. With the observation, we wish to constrain its source size, and evalute if the radio emission is due to star formation processes or not.

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) ILTJ015915 53.0 B0329+54_D 82.6 J0145+2319 49.8 J0151+2517 51.9 J0205+2416 54.2 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
