Reconstruction of the ESO 137-006 MeerKAT observation in the LO sub-band (961–1145 MHz) with fast-resolve. The radio galaxies ESO 137-006 and ESO 137-007, as well as the background sources, are modeled with independent Gaussian processes. White boxes indicate the spatial extent of each Gaussian process. Zooms on the reconstructions of ESO 137-006 and ESO 137-007 for both sub-bands are shown in Figs. 7, B.3, B.4, and B.5.
