COVER INFORMATION Station: DARNHALL (Code Da ) Experiment: Characterizing OCRs in dwarf galaxies Exp. Code: ev026f 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 J121407.57+423829.2 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 it s source size, and evalute if the radio emission is due to star formation processes or not.
