VizieR Online Data Catalog: DECam Survey of Scorpius Centaurus (Moolekamp+, 2019)

Photometric and estimated properties of M and L dwarfs in the UCL and LCC subgroups of Scorpius Centaurus. izY magnitudes are PSF magnitudes made on DECam images and calibrated using SDSS reference fields. ID's for all cross-matched objects in external catalogs (2MASS, AllWISE, etc) are also given, as entries in those catalogs were used to estimate the proper motions of our stellar and substellar candidates as described in the paper.

Some fields were observed multiple times with DECam, in which case we list proper motions estimated using decam observations only, in addition to proper motions using our DECam observations and reference catalogs.

Using the Baraffe et al. (2015A&A...577A..42B) models combined with our photometric measurements we estimated mass, Teff, age, spectral type, atmospheric extinction, and distance to each object. The tables also includes flags used for processing, including a confidence estimate as described in the paper. Some starts were saturated in the 200s exposures, so shorter 7s exposures were used and sources with entries from the short exposures are marked with a "shortexp" column name.
