Notes. ϵH(ν) ≡ Mean dust emissivity ϵH(ν) expressed as monochromatic brightness at the reference frequencies, derived from correlation of the maps with the Galactic Hi template. Not colour corrected. σstat ≡ Statistical uncertainty (1σ) of the mean emissivities. photunc (%) ≡ Uncertainties of the absolute calibration [%] from Planck Collaboration I (2014), Bennett et al. (2013), and Hauser et al. (1998). σtot ≡ Total uncertainty combining statistical and photometric uncertainties [MJy sr-1 per 1020 H cm-2]. cc ≡ Colour-correction factors in Eq. (8) computed with the greybody parameters listed in Table 3. uc ≡ Unit conversion factors from MJy sr-1 to thermodynamic (CMB) temperatures in mK.
