Polarization map from ACT DR6

Caption

The same area as in figure 8 of the paper, but this time showing polarization vectors overlaid on a total intensity map. Both the map and vectors are from an ACT DR6+Planck f090+f150 coadd to maximize S/N, but in polarization ACT completely dominates. The theoretical TE correlation is quite low and has a scale-dependent sign, so no clear visual correspondence between the intensity and polarization fields is expected.
