Existing membership catalogs span limited portions of the OSFC, reflecting the difficulty of selecting targets homogeneously across this extended, highly structured region. We have used data from wide-field photometric surveys to produce a less biased parent sample of young stellar objects (YSOs) with infrared (IR) excesses indicative of warm circumstellar material or photometric variability at optical wavelengths across the full 420deg^2^ extent of the OSFC. When restricted to YSO candidates with H<12.4, to ensure S/N~100 for a six-visit source, this uniformly selected sample includes 1307 IR excess sources selected using criteria vetted by Koenig & Leisawitz (2014ApJ...791..131K) and 990 optical variables identified in the Pan-STARRS1 3{pi} survey: 319 sources exhibit both optical variability and evidence of circumstellar disks through IR excess. Objects from this uniformly selected sample received the highest priority for targeting, but required fewer than half of the fibers on each APOGEE-2 plate. We filled the remaining fibers with previously confirmed and new color-magnitude selected candidate OSFC members. Radial velocity measurements from APOGEE-1 and new APOGEE-2 observations taken in the survey's first year indicate that ~90% of the uniformly selected targets have radial velocities consistent with Orion membership. The APOGEE-2 Orion survey will include >1100 bona fide YSOs whose uniform selection function will provide a robust sample for comparative analyses of the stellar populations and properties across all sub-regions of Orion.2018ApJS..236...27Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/236/27CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toVII/233 : The 2MASS Extended sources (IPAC/UMass, 2003-2006)II/328 : AllWISE Data Release (Cutri+ 2013)II/349 : The Pan-STARRS release 1 (PS1) Survey - DR1 (Chambers+, 2016)J/AJ/121/2124 : {lambda} Ori pre-main-sequence stars photometry (Dolan+, 2001)J/AJ/123/387 : VRI photom. of {lambda} Ori star-forming region (Dolan+, 2002)J/AJ/129/907 : New Ori OB1 members (Briceno+, 2005)J/A+A/440/403 : 109 new Galactic open clusters (Kharchenko+, 2005)J/ApJ/664/481 : Opt/IR photometry of Collinder 69 (Barrado y Navascues+ 2007)J/ApJ/661/1119 : Spectroscopy in the 25 Ori group (Briceno+, 2007)J/A+A/461/183 : Variability of classical T Tauri (Grankin+, 2007)J/ApJ/662/1067 : Sptizer observations of sigma Orionis (Hernandez+, 2007)J/A+A/485/155 : HK photometry of rho Oph PMS stars (Alves de Oliveira+, 2008)J/A+A/478/667 : The Mayrit catalogue (Caballero, 2008)J/A+A/479/827 : UBVR light curves of weak-line T Tauri stars (Grankin+, 2008)J/ApJ/674/336 : Spitzer observations of NGC 1333 (Gutermuth+, 2008)J/ApJ/697/1103 : Kinematics of Orion Nebula Cluster (Tobin+, 2009)J/ApJ/722/1226 : IR photometry in {lambda} Orionis cluster (Hernandez+, 2010)J/A+A/526/A21 : Collinder 69 X-ray sources (Barrado+, 2011)J/A+A/530/A150 : XMM observations of {lambda} Ori cluster (Franciosini+, 2011)J/A+A/536/A63 : Collinder 69 very low mass stars & brown dwarfs (Bayo+, 2011)J/AJ/144/192 : Spitzer survey of Orion A & B.
