Ratio of spectroscopic to photometric pairs (﹩N_{zz}/ N_{pp}﹩) plotted vs. angular separation (θ), with error bars computed using the Jackknife technique. Top: Data before corrective weights have been applied. A substantial deficit of spectroscopic pairs is seen at small separations (﹩\theta < 55^{\prime \prime }﹩). At larger separations, ﹩N_{zz}/ N_{pp}﹩ converges to the square of the overall spectroscopic completeness of the sample (﹩f^{2}_{s}\sim 0.78﹩), as indicated by the dashed line. The solid lines show our model fit to the data, which is used to correct for the small‐scale spectroscopic incompleteness. Bottom: Data after these weights have been applied. The corrected data points provide an excellent fit to the overall spectroscopic completeness (solid line), confirming that the small‐scale incompleteness has been successfully removed.
