Second panel (see previous page for the first one): Equivalent plot but for all Gaia EDR3 stars in the region of interest with corrected parallaxes that are compatible with the distance to Car OB1 and positive, and with catalog values of G_BP3 − G_RP3. The plotted objects are classified according to whether they are located inside or outside of the area limited by G_BP3 − G_RP3 = 1.0 and the R₅₄₉₅ = 4.5 extinction track for average MS stars with T_eff = 20 kK. Stars inside that area are further divided into those matched with objects in the first panel (154) and those unmatched (19). We note that an additional three stars inside the above-mentioned area in the first panel (HD 93 129 Ab, CPD −59 2636 A,B, and ALS 19 740) plus η Car outside of that area are not shown either because they are not included in Gaia EDR3 or have no parallaxes there.
