RM grids of polarized components in the median-filtered EL, EM, EC, and GL observations. The markers indicate the presence of a polarized component at that location in the observation. Positive RMs are red and negative RMs are blue, while the depth of the color indicates the magnitude of the RM. Circle and star markers denote Faraday simple and complex components, respectively. Plus signs indicate Faraday simple components where the RM is consistent with 0 within the uncertainty. The color scale of the background total intensity image is the same as in Figure 1.
