pair of main-sequence stars with a small [$\mathit{q}$]{}, thereby observing the systems as SB2s. Because our target sample contains a wide range of binary types, including EBs with small [$\mathit{q}$]{}, EBs with equal mass components, and EBs with one or both components evolving or evolved, the suitability of optical or NIR spectroscopy for solving each EB as an SB2 is determined on a case by case basis.

We analyze our processed APOGEE and HET spectra identically, using a combination of one-dimensional and two-dimensional cross-correlation algorithms to measure RVs for the primary and secondary components of each EB. For the two-dimensional case, we have implemented the TODCOR algorithm [@1994ApJ...420..806Z] as an interactive IDL program, SXCORR, which allows the user great flexibility in quickly optimizing the correlation templates while examining multiple epochs of spectra. SXCORR simultaneously cross-correlates two template spectra against a target spectrum containing the blended light from a binary to disentangle the component RVs. Our SXCORR implementation of TODCOR includes the maximum-likelihood extension described by @2003MNRAS.342.1291Z, modified slightly to allow segments of spectrum with variable lengths. SXCORR automatically resamples both target and template spectra into log-lambda wavelength space [@1979AJ.....84.1511T], as needed depending on the input spectra.
