Data releases

Preliminary

The preliminary LoTSS data release is described by Shimwell et al. (2017). It consists of 350 square degrees in the region of the HETDEX Spring field imaged at a resolution of 25 arcsec and a typical noise level less than 0.5 mJy/beam. Over 35,000 sources are detected.

Data release 1

LoTSS data release 1 (DR1) is described by Shimwell et al. (2018). It consists of images at the full resolution (6 arcsec) and sensitivity (better than 0.1 mJy/beam) of 400 square degrees in the region of the HETDEX Spring field. Over 325,000 sources are detected.

Images and catalogues from DR1 will be available on publication of the Astronomy and Astrophysics special issue describing the survey and its results, coming in January 2019.

Data release 2

Preparations for a second data release are under way. We aim to release images and catalogues for 2000 square degrees of the northern sky by 2020.
