Fig. 5

Images representing the entire primary beam. Centred on RA Dec +29°41′32''̣5. Each pixel represents a field 6.5″ × 5″. The flux density in Jy beam-1 is shown for the brightest pixel in each image and the rms of all of the pixels both with and without primary beam correction applied: a) peak flux density no PB correction; b) rms flux density no PB correction; c) Peak flux density PB correction; d) rms flux density PB correction. The brightest point (towards the top-right) is the A component, attenuated since a simple model of A has been subtracted from the UV data. All flux apart from the brightest pixel in each image is spurious flux from the sidelobes of A or noise.
