Abstract

This work is based on studies of {rho} Oph and L1688 from 11 papers. Additionally, three surveys were selected for cross-matching with our literature sample to obtain astrometric data (proper motions, and radial velocities) of the sources, which is essential for identifying new sources with the algorithm. Proper motions and parallaxes were obtained from Gaia EDR3 (Gaia Collaboration et al., 2020A&A...649A...1G, Cat. I/350). To complement Gaia astrometry and constrain the models of the algorithm, we combine it with radial velocities from APOGEE-2 (Majewski et al., 2017AJ....154...94M, Cat. III/284), a large-scale spectroscopic survey conducted in the near-infrared, and Gaia-ESO (Gilmore et al., 2012Msngr.147...25G), a spectroscopic survey by the European Southern Observatory (ESO) combined with the Gaia astrometry catalog. Radial velocities from these surveys deliver superior resolution and statistics compared to radial velocities from Gaia. We applied the classification strategy described in Ratzenboeck et al. (2012A&A...539A..64A) for identifying new members of the {rho} Oph region in the Gaia EDR3 catalog. (1 data file).
