Kiel diagram (top panel, using quantities from the SSPP pipeline), and the color-magnitude diagram (bottom panel) for stars likely associated with the Orphan stellar stream color-coded based on the probability and with varying point size denoting the metallicity. The blue and red lines represent isochrones from the MESA Isochrones and Stellar Tracks (MIST, Dotter 2016; Choi et al. 2016; Paxton et al. 2011, 2013, 2015) database for two different metallicities. The gray contours in the top panel represent the entire star matched sample of SDSS-Gaia.
