VizieR Online Data Catalog: M-dwarf multiples in the SDSS-III/APOGEE (Skinner+, 2018)

The SDSS-III (Eisenstein et al. 2011AJ....142...72E) APOGEE M-dwarf ancillary program (Deshpande et al. 2013, J/AJ/146/156; Holtzman et al. 2015AJ....150..148H) was designed to produce a large, homogeneous spectral library and kinematic catalog of nearby low-mass stars; these data products are useful for investigations of stellar astrophysics (e.g., Souto et al. 2017ApJ...835..239S; Gilhool et al. 2018, J/AJ/155/38) and refining targeting procedures for current and future exoplanet search programs. These science goals are uniquely enabled by the APOGEE spectrograph (Wilson et al. 2010SPIE.7735E..1CW, 2012SPIE.8446E..0HW), which acquires high-resolution (R~22000) near-infrared spectra from each of 300 optical fibers. As deployed at the 2.5 m SDSS telescope (Gunn et al. 2006AJ....131.2332G), the APOGEE spectrograph achieves a field of view with a diameter of 3°, making it a highly efficient instrument for surveying the stellar parameters of the constituents of Galactic stellar populations (Majewski et al. 2017AJ....154...94M). The SDSS DR13 data release (Albareti et al. 2017ApJS..233...25A) includes 7152 APOGEE spectra of 1350 stars targeted by this ancillary program. We used the TODCOR algorithm (Zucker & Mazeh 1994ApJ...420..806Z) to measure RVs from all HET/HRS spectra and any APOGEE spectra flagged with low-RV separations. This TODCOR analysis followed the procedures previously discussed by Bender et al. (2005AJ....129..402B) and used the algorithm implementation of Bender et al. (2012ApJ...751L..31B).
