VizieR Online Data Catalog: Radial velocities & photometry of AD Leonis & GJ 674 (Tuomi+, 2018)

Spectroscopic data of AD Leo were obtained from two sources. We downloaded the publicly available data products of HARPS (Mayor et al. 2003Msngr.114...20M) from the European Southern Observatory archive and processed them with the TERRA algorithms of Anglada-Escude & Butler (2012, J/ApJS/200/15). As a result, we obtained a set of 47 radial velocities with a baseline of 3811 days and root-mean-square (rms) estimate of 22.59 m/s. To study the photometric variability of AD Leo, we obtained ASAS (Pojmanski 1997AcA....47..467P; 2002, Cat. II/264) V-band photometry data (http://www.astrouw.edu.pl/asas) from the ASAS-North (ASAS-N) and ASAS-South (ASAS-S) telescopes. We only selected the "Grade A" data from the set, removed all 5σ outliers, and obtained sets of 316 and 319 photometric measurements with baselines of 2344 and 2299 days, respectively.
