Catalog Service: LoTSS-DR1 Cross-Matched Source Catalogue
Description
This service queries the catalog of radio sources from the LOFAR Two-metre Sky Survey First Data Release (LoTSS-DR1) that have been cross-matched with an optical or infrared counterpart. This data release contains images and catalogs that characterise the low-frequency radio emission in the region of the HETDEX Spring Field (right ascension 10h45m00s to15h30m00s and declination 45◦00′00′′ to 57◦00′00′′). A total of 325,694 radio sources are detected in a region covering 424 square degrees. The maps have a median sensitivity of 71 uJy/beam and a resolution of 6 arcsec. Optical counterparts for 71% of the radio sources have been identified and where possible photometric redshifts for these sources have been derived.
