VizieR Online Data Catalog: OCCAM. IV. Open cluster abundances using APOGEE DR16 (Donor+, 2020)

Our primary source of chemical abundance and radial velocity (RV) data is the Sloan sky Digital Survey (SDSS) sixteenth data release (DR16, H. Jonsson et al. 2020, in preparation) taken as part of the second, dual-hemisphere phase of Apache Point Observatory Galactic Evolution Experiment (APOGEE 2; Majewski+ 2017AJ....154...94M). APOGEE is a high-resolution, near-infrared spectroscopic survey currently operating in both hemispheres, at Apache Point Observatory (APO, New Mexico) and Las Campanas Observatory (LCO; Chile). The APOGEE/DR16 data set includes about 430000 stars, collected between 2011 August and 2018 August using the two 300-fiber APOGEE spectrographs.

Our secondary source of data is Gaia DR2 (I/345); we use photometric and astrometric data, radial velocity measurements, and parallax values in common with APOGEE.
