The above candidate appeared as a significant (9.1 ) overdensity of stars against the density field of foreground stars (top left) and background galaxies (top right). In color magnitude-space (bottom left), this candidate displays a clear main sequence turnoff, lower red giant branch, and blue horizontal branch. The radial profile of stars about the centroid (bottom right) is consistent with the Plummer profile of a compact system with scale extension of ~1 arcmin.
