We have tested our methods on a Faraday dispersion function with four Faraday thin sources. From left to right in the first row are: a) original F(φ); b) dirty curve; c) RM-CLEAN. From left to right in the second row are: d) CS-RM-Thin; e) CS-RM-Thick; f) CS-RM-Mix. The thin solid line shows the real value, the dashed line the imaginary part, and the thick solid line the amplitude. All horizontal axis units are rad m^-2, i.e. φ, and all vertical axis units are Jy m² rad^-1.
