Effect of the cut-off in Π in the projection of the three-dimensional correlation functions along the line of sight. Shown is the ratio of the projected correlation function computed for     h^-1 Mpc over the correlation function obtained with     h^-1 Mpc, for both the galaxy clustering signal (gg, in black) and number density-shape correlations (g+, in red). Points are computed from the MegaZ-LRG data, using the full range in redshifts. Note that the black points have been slightly offset horizontally for clarity. The black line is obtained from the model for w_gg. The red hatched region comprises the range of ratios for w_g +  with different relative strengths of the galaxy-galaxy lensing contribution. The red solid line indicates the ratio resulting for the best-fit intrinsic alignment amplitude determined in Sect. 5.3. Note that the error bars at different transverse separations are correlated, in particular for w_gg at large r_p, see Fig. 6.
