As in Fig. 6 but showing three models fit to the data. Red lines indicate the standard fit used to measure the BAO parameters (Sect. 5.2), blue lines the standard fit if the velocity distribution of quasars was null, and green lines the standard fit with the addition of a broadband defined by (33) with (i_min,i_max,j_min,j_max) = (0,2,0,6). The cross-correlation is multiplied by a factor r² to show the BAO scale.
