Gaia EDR3 chart of the 1 ° ×1° field centered on Villafranca O-024 (γ Vel cluster). Plotted sources are those with G <  18 and with normalized parallaxes within 3 sigmas independently of other filters i.e., a lax selection criterion for cluster membership rather than the strict one used to select the sample in this paper. Symbol color, symbol size, and arrows encode , G′, and proper motion, respectively, according to the caption. Objects without color and arrows are those with a proper motion separation larger than 1.35 μas/a. The yellow star marks the location of γ² Vel (not a Gaia EDR3 source) and the large circle the circular aperture used to select cluster sources.
