cds-question@unistra.frmilky-way-galaxystellar-associationsgiant-starsLarge pristine samples of red clump stars are highly sought after given that they are standard candles and give precise distances even at large distances. However, it is difficult to cleanly select red clumps stars because they can have the same Teff and logg as red giant branch stars. Recently, it was shown that the asteroseismic parameters, {DELTA}P and {DELTA}{nu}, which are used to accurately select red clump stars, can be derived from spectra using the change in the surface carbon to nitrogen ratio ([C/N]) caused by mixing during the red giant branch. This change in [C/N] can also impact the spectral energy distribution. In this study, we predict the {DELTA}P, {DELTA}{nu}, Teff and logg using 2MASS, AllWISE, Gaia, and Pan-STARRS data in order to select a clean sample of red clump stars. We achieve a contamination rate of ~20%, equivalent to what is achieved when selecting from Teff and logg derived from low resolution spectra. Finally, we present two red clump samples. One sample has a contamination rate of ~20% and ~405000 red clump stars. The other has a contamination of ~33% and ~2.6 million red clump stars which includes ~75000 stars at distances >10kpc. For |b|>30 degrees we find ~15000 stars with contamination rate of ~9%. The scientific potential of this catalog for studying the structure and formation history of the Galaxy is vast given that it includes millions of precise distances to stars in the inner bulge and distant halo where astrometric distances are imprecise.2020MNRAS.495.3087Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/495/3087CatalogResearchIsServedByTAP VizieR generic
