Fig. 11.
LBA wide-field image after DIE calibration. The rms background noise is ≈2.0 mJy beam−1 at a resolution of 42″ × 30″. The DDE calibrator directions are highlighted in red, the blue dashed circles show the primary beam FWHM of the LOFAR 2.0 LBA at 54 MHz and the HBA at 144 MHz. The background color scale shows the logarithmic surface brightness in arbitrary units.
