Fig. 3


Distribution of the sources that define the combined curvilinear and Gaussian likelihood model (the final reference set after all EM iterations) in the same 2D projections used in Fig. 1 (the VPD, and the (i − K)–K, (r − K)–K, and (i − K)–i CMDs). Black circles represent sources in the initial reference set that were removed during the EM iterations, and black crosses represent complete sources added in the iterative process. Orange dots represent sources in both the initial and final reference sets.
