Differences between the maps produced by Algorithms 0 and 1 from typical eight-hour scans (here the P26HETDEX03 pointing in the Hobby-Eberly Telescope Dark Energy Experiment, HETDEX, field, see Shimwell et al. 2017). 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 part of the P26Hetdex03 8 hours LOFAR-HBA scan as imaged by Alg. 0. (b) Region (1) as imaged by Alg. 0. (c) Region (1) as imaged by Algorithm 1. (d) The central part of the P26Hetdex03 eight-hour LOFAR-HBA scan as imaged by Algorithm 1. (e) Region (2) as imaged by Algorithm 0. (f) Region (2) as imaged by Algorithm 1.
