Table information for 'apertif_dr_bootes.source_catalog'

General

This table is available for ADQL queries and through the TAP endpoint.

Resource Description: Apertif is a phased-array feed system for the Westerbork Synthesis Radio Telescope (WSRT), providing forty instantaneous beams over 300 MHz of bandwidth. This data release includes the catalogue and image observed by Apertif covering 26.5 square degree region in the Boötes constellation at 1.4 GHz. The image is a mosaic of 187 Apertif images from 8 different survey observations performed between April 2019 and November 2021. It has an angular resolution of 27×11.5 arcseconds and a median background noise of 40 μJy/beam. From this mosaic, 8994 sources were extracted and the catalogue is complete down to the 0.3 mJy level.
