As in Fig. 5 but with parallaxes corrected according to Eq. (7) in consecutive steps (see main text). The bottom panel shows the applied correction (Eq. (7)) as the black line. The small black, red, and green circles represent the L20 correction for β = 0, −60, and +60°. There is an offset as the L20 corrections are absolute, while the corrections applied to the WB sample are relative to the correction at G = 20 mag.
