Photometric main sequence turnoff point distances along declination for the Orphan stream. Our data point (blue circle) is based on the theoretical isochrone for a 10.0 Gyr old stellar population with [Fe/H] = −1.63. The other values correspond to Belokurov et al. (2007a, green triangles), Newberg et al. (2010, orange diamonds) and Casey et al. (2006, cyan star).
