Notes. The table lists: mean redshifts ⟨z⟩, mean r-band luminosities relative to the pivot L_piv = L(M_r = −22), the number of galaxies used as tracers of the intrinsic shear field N_shapes, and the number of density field tracer galaxies N_positions – we do not apply colour-selections to positional tracers for our intrinsic alignment correlations, using the full sample to trace the density field (see Sect. 4.2). Samples labelled ‘Qz₅₀’ are defined from the best 50% of photo-z in all of PAUS W3 (i.e. selected on photo-z quality prior to the colour-cut). GAMA galaxies are those analysed by Johnston et al. (2019), who limited the blue density sample objects to M_r ≤ −18.9, causing the blue sample to have more shapes than density tracers.
