Notes. The radius of the annulus considered is given in degrees and in kpc in the first column; the value of 744 kpc (Vilardell et al. 2010) is adopted for the distance to M 31. The second column indicates the region considered. In the third column the numbers of pixels in each region are given. The fourth column shows the CMB mean temperature of each region (in μK) in the 100 GHz Planck map with the corresponding standard error (SE), while the last column gives the average temperature excess in the 360 control fields with the standard deviation (see text for details).
