Comparison between the LOFAR-HBA maps generated at 150 MHz by Retana-Montenegro et al. (2018) and in the current work. The color scale is the same on all panels and is displayed using an inverse hyperbolic sine function to render both the low level artifacts and some bright sources. (a) The central ≳ 2 deg² part of the Bootes field as imaged by the direction dependent factor algorithm (Retana-Montenegro et al. 2018). (b) Zoom in on region (1) of the map synthesised by Retana-Montenegro et al. (2018). (c) Zoom-in on region (1) of the map synthesized by kms-ddfacet (this work). (d) The same as in 12a, but imaged with Algorithm 2. (e) Zoom-in on region (2) of the map synthesized by Retana-Montenegro et al. (2018). (f) Zoom-in on region (2) of the map synthesized by kms-ddfacet (this work).
