Fitted projected separation ρ and magnitude difference ﹩\vartriangle m﹩ for the resolved pairs (large plus signs) and the partially resolved pairs (small plus signs with line segments showing the displacement from ﹩\vartriangle m=0.0﹩ to 0.4, i.e., for ﹩{{F}_{2}}/{{F}_{1}}=1.0﹩ to 0.7). The diamonds connected by a solid line represent the expected faint limits for detection by the cross correlation method and the dotted line shows the corresponding faint limit for detection by the second derivative test (Caballero-Nieves et al. 2014).
