Top row: example 4.5°×4.5° mosaics centered on the TGSS pointing R15D26 as found in ADR1 (left; 3.5 mJy beam^-1 noise) and in DR5 (right; 6.7 mJy beam^-1 noise). Both mosaics are displayed using the same color scale. Besides a higher overall noise level, the DR5 mosaic also shows residual sidelobe structure near brighter sources (≳ 1 Jy) as compared to the ADR1 mosaic. Bottom row: a 2°×2° zoomed-in version of the top row mosaics, showing more detail.
