Comparisons of the BV CMD with PARSEC and Dartmouth isochrones of various parameters. The grey points are all the stars in our photometry, and the radial velocity members are marked in red. Left-hand side panels: the best-fitting PARSEC isochrone (solid blue line) corresponds to an age of 316 Myr, a solar metallicity, a reddening E(B − V) = 0.40 and a distance modulus (V − M_V) = 11.45. The four panels show the change in the isochrone when modifying the extinction, distance modulus, age and metallicity with respect to the best-fitting isochrone. Right-hand side panels: same procedure with Dartmouth isochrones. The best-fitting isochrone is the solid green line. In all cases, the data are uncorrected for extinction. The isochrones are shifted along the extinction vector.
