Top: raw distributions of MV and (VI) of all Hipparcos stars within 50 pc (6911 objects). The dashed lines show the numbers of stars within the completion volume corresponding to their magnitude (see text). Middle: local debiased volumic density of stars (per magnitude unit, in pc-3) estimated from the ratio of stars within the completion volume and extrapolated beyond MV = 6. Bottom: debiased MV vs. VI stellar density of stars closer than 50 pc.
