LoTSS data release 1 (DR1) is described by Shimwell et al. (2019). It consists of images at the full resolution (6 arcsec) and sensitivity (better than 0.1 mJy/beam) of Dutch LOFAR at a central frequency of 144 MHz over 400 square degrees in the region of the HETDEX Spring field. Over 325,000 sources are detected. The data release includes optical counterparts for 71% of the radio sources (Williams et al. 2019) and photometric redshifts for these sources (Duncan et al. 2019).
