Complexity metric values resulting from the uniform slab (left panels) or turbulent screen (right panels) models for different S/N and Faraday thickness values. The complexity metrics shown are σadd,C (top row) and M2 (bottom row). Each pixel was derived from a single polarized spectrum realization, so inter-pixel variations indicate the influence of spectral noise on the resulting metric value. Blank (white) values in the M2 plots occur occasionally at low S/N when the resulting FDF contains no samples above the CLEAN threshold and, thus, no clean components with which to compute the second moment.
