Notes. For each region, fsky is the initial sky fraction, its value after point source masking and apodization, I353 the mean specific intensity at 353 GHz within the region, in MJy sr-1, and NH i the mean H i column density, in units of 1020 cm-2 (Kalberla et al. 2005). For the power-law fits in multipole , we also list the exponents αEE and αBB (Sect. 4.2), the χ2 of the fits with fixed exponents αEE = αBB = −2.42, the value AEE of the fitted amplitude at = 80 (in μK at 353 GHz, Sect. 4.3), and the mean of the amplitude ratio ABB/AEE (see Sect. 4.4).
