Sloan filter i vs. i − z, i vs. r − i, and i vs. g − i absolute magnitude–color diagrams for YSOC stars. Isochrones are from MIST (Paxton et al. 2011; Choi et al. 2016; Dotter 2016) with parameters [Fe/H] = 0, v/v _critical = 0.4, and Av = 0. The Red dashed line on the g − i diagram shows a cutoff for stars we deem to be likely background due to high reddening.
