To enable thorough scientific exploitation of the data, in LoTSS-DR2 a wide variety of different data products are being made publicly available with DOI:10.25606/SURF.LoTSS-DR2 and can be accessed via the LOFAR surveys webpage, the ASTRON Virtual Observatory and the SURF Data Repository. More specifically, this data release includes the following Stokes I products:

Product.A1 Mosaiced astrometric-corrected Stokes I 6′′ resolution 120-168 MHz restored images with associated PYBDSF residual and noise maps.

Product.A2 Mosaiced Stokes I 20′′ resolution 120-168 MHz restored images.

Product.A3 Individual Stokes I 6′′ (with and without astrometric correction) and 20′′ resolution 120-168 MHz restored images with associated DDFacet model, residual and mask images.

Product.A4 Individual Stokes I 6′′ (with astrometric correction) resolution 16 MHz bandwidth images with central frequencies of 128, 144 and 160 MHz.

Product.A5 Catalogue of 4,396,228 radio sources and the 5,121,366 Gaussian components that describe them.

Product.A6 Hierarchical Progressive Surveys (see Fernique et al. 2015) images to visualise the mosaiced Stokes I 6′′ and 20′′ resolution images.

In addition, the following polarisation products are included in this data release:

Product.B1 Individual observation Stokes QU 20′′ resolution undeconvolved 480-plane image cubes with a frequency resolution of 97.6 kHz.

Product.B2 Individual observation Stokes QU 4′ resolution undeconvolved 480-plane image cubes with a frequency resolution of 97.6 kHz.

Product.B3 Individual observation Stokes V 20′′ resolution 120-168 MHZ continuum undeconvolved images.

And finally the following uv-data and calibration products are included for each pointing:

Product.C1 DI calibrated visibilities and DD calibration solutions.

Product.C2 Facet layout and astrometric corrections
