Notes. PMN J1539−1128 has two values corresponding to two different observations (see Table 1). Columns are: Source name; delta time (days), which is the difference in time between our observation(s) date and the nearest ZTF observation; magnitude at nearest date; median, minimum, maximum magnitude of the source; and measured redshift. ( * )i magnitude.
