Example field observed in band-4 during a night with all antennas functioning, uncorrected for primary beam attenuation, in the native equatorial coordinates. The white circle marks the region used for mosaicking. The beam size is 12″ × 7″, and the rms noise is about 0.3 mJy beam⁻¹. The colormap and the limits are chosen such that the low-level noise features and the negative sidelobes are seen clearly.
