Cosmic Web Environmental Densities from Monte Carlo Physarum Machine for galaxies observed in SDSS and eBOSS
Value Added Catalogs
In addition to the primary SDSS photometry and spectroscopy, there are a few extra catalogs created by our collaborators that are distributed through the SAS.
Value-Added Catalogs (VACs) for all data releases, including updates to some of these, are available from the Value Added Catalogs page of the DR17 website.
Catalog of distances, extinctions, and stellar parameters of APOGEE DR17 stars combined with Gaia EDR3, derived with the Bayesian isochrone-fitting code StarHorse.
Stellar and orbital parameters for APOGEE DR17 stars, derived with the astroNN deep-learning code.
Catalog of red clump stars in the APOGEE sample.
Catalog of emission line galaxies - Lyman alpha emitters lensing candidates.
Catalog with posterior samplings in Keplerian orbital parameters for APOGEE-2 DR17 stars, derived with The Joker.
