VizieR Online Data Catalog: Precision cluster abund. for APOGEE using SDSS DR14 (Donor+, 2018)
Abstract
The primary spectroscopic data for OCCAM comes from the APOGEE (Majewski et al. 2017AJ....154...94M), which is part of the Sloan Digital Sky Survey-III and IV surveys (SDSS; Eisenstein et al. 2011AJ....142...72E; Blanton et al. 2017AJ....154...28B), utilizing the 2.5 m Sloan Foundation telescope (Gunn et al. 2006AJ....131.2332G) at Apache Point Observatory. APOGEE is a near-infrared (1.514-1.696 μm) spectroscopic survey, primarily focusing on the Galactic disk (Zasowski et al. 2013AJ....146...81Z, 2017AJ....154..198Z). The survey uses multi-fiber spectrographs (Wilson et al. 2012SPIE.8446E..0HW), allowing for simultaneous observations of 300 stars. The targets selected for analysis were observed from 2011 August to 2014 July (APOGEE-1), and from 2014 July to 2016 July (APOGEE-2). These data were released as part of the 14th Data Release of SDSS (DR14; Abolfathi et al. 2018ApJS..235...42A), which included APOGEE data for over 250000 stars. For this study, we analyzed all stars within 2x the cluster radius (Kharchenko et al. 2013, J/A+A/558/A53) for 19 clusters that resulted in a sample of 1361 stars.
