GMM results for the composition of the leptonic component; logarithmic scaling. The predictions are computed from the GMM trained with K = 3 Gaussians and n = 30 data sets neglecting the γ-ray signal maps. The predictions are determined from the CPD marginalized over the γ-ray component maps. Panel a: preditiction of the leptonic component given the radio continuum emission, and the Planck LFI and the X-ray regime. Panel b: difference between the prediction of the leptonic component given all frequency regimes except the γ-ray regime (Fig. 7d) and the selection of frequency regimes of Fig. 9a, rms = 0.16. Panel c: preditiction of the leptonic component given the CO-line emission, and the Planck HFI and the infrared regimes. Panel d: difference between the prediction of the leptonic component given all frequency regimes except the γ-ray regime (Fig. 7d) and the selection of frequency regimes of Fig. 9c, rms = 0.23.
