Two-dimensional histogram of polarization vs radius (left) and polarization angle vs arctan(y/x) (right) for all pixels in the moonlit sky in I band for FORS2. Shown are the radial fits of a cubic polynomial with and without forcing P(r = 0) = 0 (pink dashed and solid lines, respectively). The radial fit for FORS1 from PR06 is also shown (black line).
