Left: dereddened CMD for the pointing containing the Orphan stream as its secondary feature; the template main sequence function and the turnoff point (green) are plotted for the maximum of the secondary cross-correlation. We have randomly removed 60% of the stars contributing to the primary detection, which corresponds to the bright arm of the Sgr stream. Right: weighted-density diagram resulting from the secondary cross-correlation. The maximum (white bin, black cross) marks the top left corner of the template-MS function at the position of the Orphan stream’s main sequence. The primary detection has been removed, and thus it does not show in the density diagram.
