v sin i measurements of NGC 2477 member stars from Gaia DR3 data. MESA isochrones with rotation (Prot_i = 3 days) and without are shown as red and blue solid lines, respectively. The isochrones have an age of 1.0 Ga with a [M/H] of 0.1 dex, assuming E(B−V)_bkg = 0.29 mag. The MESA isochrone with rotation that we constructed has missing masses in the RGB branch and therefore we do not see the full red giant branch in this figure.
