Notes. Tb(23 GHz) ≡ Brightness temperature, in μK cm2 H-1, of AME at 23 GHz for models 1 and 2. νp and − m60 ≡ Peak frequency in gigahertz and slope at 60 GHz of AME spectrum in Eq. (10) for models 1 and 2. AWNM and ACNM ≡ Maximum brightness temperature of WNM and CNM SPDUST spectra, in μK cm2 H-1, for models 3 and 4. νshift ≡ Frequency shift in gigahertz of the CNM SPDUST spectrum for models 3 and 4. τBB ≡ Specific opacity of the blackbody component, in cm2H-1, for models 2 and 4. σH(353 GHz) ≡ Specific dust opacity at 353 GHz of greybody in cm2H-1. βmm ≡ Spectral index of the greybody component. The spectral index is fixed to 1.65 for models 2 and 4. The temperature is 19.8 K for the greybody and blackbody components for all models. χ2/ DOF ≡χ2 of the fit per degree of freedom.
