Results of the three-plane fit for RX J0852. (a)–(f) Maps of ΔN _g(3) (left panels) and ﹩{\widehat{N}}_{{\rm{g}}}(3)﹩ (right panels) for the pixel groups 1 (ΔN _g(1) > 0.1, top panels), 2 (−0.1 ≤ ΔN _g(1) ≤ 0.1, second row panels), and 3 (ΔN _g(1) < − 0.1, third row panels). The superposed contours in each panel are identical to those in Figure 1. (g) A plot of ΔN _g(3) with respect to ﹩{\widehat{N}}_{{\rm{g}}}(3)﹩. The horizontal and vertical error bars shown in the left bottom corner indicate the median values of ﹩\sigma ({\widehat{N}}_{{\rm{g}}}(3))﹩ and σ(ΔN _g(3)), respectively. The red circles and error bars denote pixel group 1, and the orange and blue ones denote pixel groups 2 and 3, respectively.
