Comparison of resolve with MEM for the simulated low-noise observation of Sect. 3.1. The images are 100² pixels large, the pixel size corresponds to roughly 0.2 arcsec. The brightness units are in Jy/px. The ridge-like structures simply stem from taking the absolute value and mark zero-crossings between positive and negative errors. First row left: resolve reconstruction. First row right: absolute per-pixel difference between the signal and the resolve reconstruction. Second row left: MEM reconstruction using the radio astronomical software package CASA. Second row right: absolute per-pixel difference between the signal and the MEM reconstruction.
