Posterior mean maps of the amplitude of each of the four intensity foreground components included in the BEYONDPLANCK analysis. Top left: synchrotron amplitude, evaluated at 30 GHz and smoothed to 2° FWHM resolution. Top right: free-free amplitude, evaluated at 40 GHz and smoothed to 30′ FWHM resolution. Bottom left: AME amplitude, evaluated at 22 GHz and smoothed to 2° FWHM resolution. Bottom right: thermal dust amplitude, evaluated at 545 GHz and smoothed to 10′ FWHM resolution. The color bars vary between panels. See Andersen et al. (2023) for further discussion of these maps.
