Parameter maps of the normalisation per arcmin², illustrating the surface brightness of the diffuse emission, for the two thermal components (vapec1, vapec2) and the powerlaw component. The images are shown in log-scale. The letters W, X, Y, Z in the labels correspond to the exponents of the marks of the colour scale. The red plus sign indicates the position of the star cluster RMC 136,the yellow cross that of SNR/PWN N157B. The lower right panel shows Hα (red), [S II] (green), and [O III] (blue) images of MCELS in three-colour presentation.
