Predicted distances for our final sample of stars on the stream coordinate system, (Λ, B), shown in the top and bottom panel, respectively (Law & Majewski 2010). Contours show stellar density for the predicted distances, ypred, on the clean sample. Points show the location of RR Lyrae stars selected as Sgr members in our training set. The average distance measured on the training sample is marked by a black horizontal line. Residuals measured from the NCV on the training list are shown as Dtrue − Dpred along both coordinates. Red dashed lines show a linear fit to the training data and residuals. The parameters of the fits are shown in the top right part of each plot. For clarity, only the error bars of the residuals are shown. The typical error for the RR Lyrae star distances is ∼1.16 kpc (see Appendix C.1.1).
