CMDs for the F162M, F182M, and F200W filters. Overplotted are solar (dotted lines in blue) and half-solar 1 Myr isochrones (solid lines in red) from Baraffe et al. (2015) using the atmospheres from Allard (2014). To illustrate the location of the extinction-limited samples, the isochrones have also been shifted by A_V = 15. The locations of 0.6 M_⊙ and 0.075 M_⊙ stars are shown, the latter being the lowest mass of the half-solar metallicity isochrone. The 0.6 M_⊙ for a 1 Myr isochrone is also the brightest object considered in the fits to the IMF. The extinction vector corresponding to A_V = 15 is shown in the CMDs for the cluster field. Bottom panels: similar data points as in the upper panels, but for the control region. A 1 Myr solar metallicity isochrone, shifted to the distance of S284, is shown.
