Comparison of G absorption values derived by the GSP_Phot module of the Apsis pipeline (ag_gspphot; Creevey et al. 2023) and the values derived by the SOS pipeline (g_absorption) for 84 501 RRab stars for which both estimates are available. The A(G) values are colour-coded according to the intensity-averaged G magnitudes of these RR Lyrae stars, as encoded in the colour scale on the right (see text for details).
