Apertif DR2 - Continuum images

Apertif is a phased-array feed system for the Westerbork Synthesis Radio Telescope (WSRT), providing forty instantaneous beams over 300 MHz of bandwidth. A description of the second data release is to be included here. This service queries the continuum images from the second data release of Apertif. Multi-frequency synthesis (mfs) Stokes I images are produced over the full frequency range (1292.5– 1430 MHz) and saved as fits files for each beam. The size of the continuum images is 3.4 deg × 3.4 deg (3073 × 3073 pixels, with 4''/pixel). The median noise in the continuum images is 41.4 uJy/beam and the median angular resolution is 11.6''/sin(declination). A companion VO table provides a continuum source catalog based on all continuum images contained in this data release and is described in Kutkin et al. (2022) (see https://vo.astron.nl/apertif_dr2/q/apertif_dr2_catalogue/form).
