COVER INFORMATION Station: KNOCKIN (Code Kn ) 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.
