Accuracy of the recovered peak column density (left frames) and FWHM (right frames) values for compact sources, estimated with method E at the resolution of 12.0″. The upper frames correspond to a noise level of kn = 0.1 and the lower frames to kn = 0.3. The blue and the red symbols correspond, respectively, to the 10 K and 20 K sources. Values outside the range of [–0.6, 0.6] are plotted at those boundaries. To reduce the overlap of plot symbols, some jitter has been added to the x-axis values of the FWHM plots.
