This page presents the data release of the LOFAR international baseline wide-field images and catalogues of the ELAIS-N1 field at 0.3”, 0.6”, and 1.2” resolutions. The images reach a best sensitivity of 14 µJy/beam at 0.3”, 21 µJy/beam at 0.6”, and 40 µJy/beam at 1.2” using four 8h observations, making these the currently deepest LOFAR wide-field images at these resolutions. Above 5 sigma, 9203 sources at 0.3”, 8566 sources at 0.6”, and 5869 sources at 1.2” are detected within the 2.5 x 2.5 degrees field of view.
The image was produced following the procedure described by de Jong et al. (2024)., where 30 directions were self-calibrated. The corresponding 30 facets were imaged separately, and in each facet we ran PyBDSF to construct catalogues, which were merged together into a single catalogue for each resolution. We also supply a mosaic image where the 30 facets have been convolved to a common resolution of 0.36 x 0.45, 0.58 x 0.62, and 1.0 x 1.5 arcsecs before mosaicing. This mosaic is provided for convenience of browsing only and we recommend users to extract sub-images from the individual facets if possible. The facet layout is shown to the right.
For 6-arcsec products for ELAIS-N1 please see the release page for DR2 of the 6-arcsec deep fields survey.
