Notes. patches where both synchrotron and thermal dust are detected in the ℓ₈₀ bandpower and with recovered values for r_FG,min< 0.12 (first four rows) and regions where the upper limit on r_FG,min is below ~0.06 (remaining sixteen entries). From left to right: HEALPix pixel number, direction of the center, r_FG,min, frequency of minimum emission, frequencies corresponding to synchrotron and dust being negligible within the quoted threshold, region class.

^(a)

Pixel number of the HEALPix N_side = 8 grid (enumeration starts from zero, ring ordering) associated with the circular region for which spectra are evualated.

^(b)

Galactic coordinates of the region center.

^(c)

Region class as defined in Table 2.
