Notes. We list the reduced χ² and the corresponding p-values of a zero signal fit to the correlation function w_g × , and to w_g +  for large values of  |Π| . We use 270 <  |Π| / [h^-1Mpc]  < 315 for the photometric MegaZ-LRG data and 100 <  |Π| / [h^-1Mpc]  < 150 for the spectroscopic SDSS Main samples. We include all transverse scales available into the fit (third and fourth columns), but also restrict r_p to scales larger than 6    h^-1 Mpc (fifth and sixth columns), i.e. the range in which the intrinsic alignment fits were performed. The numbers in parentheses indicate Π_max in units of     h^-1 Mpc for the MegaZ-LRG samples.
