Notes. (1) name of star, (2), (3) Galactic coordinates of star, (4) spectral type, (5) Gaia DR3 corrected parallax and parallax uncertainty, (6) distance estimated by Bailer-Jones et al. (2021) with uncertainty, (7) (8) Gaia DR3 galactic proper motion and proper motion uncertainty, (9) radial velocity, (10) and (11) transverse and peculiar velocity relative to LSR, respectively, (12) transverse or peculiar (italic)) velocity relative to Vel OB1, (13) distance from the Galactic plane, (14) observed bow shock, (15) alignment status of observed bow shock, and (16) mis-alignment angle. Two objects are indicated as DR3 N72 and N60 based on their last numbers of source_id from Gaia DR3. Objects in common with Carretero-Castrillo et al. (2023) are in bold. (P) - objects included in Patten et al. (2025).
