Comparison between the CMD of the bona fide stars in the eMSTO region of NGC 1783 and a set of PARSEC rotating isochrones (red curves) computed for an age of 1.5 Gyr, a metallicity of [Fe/H] = − 0.35 and different initial rotation rates (ωi = 0.0, 0.5, 0.9). In each panel the same set of isochrones is shown while varying the inclination angles of the rotation axis with respect to the line of sight, i = 0° (left), i = 60° (central), and i = 90° (right). The targets are color-coded according to their vsini values.
