VizieR Online Data Catalog: Probing the Gal. halo with RR Lyrae stars. I. (Liu+, 2020)

To collect known RRLs, we use the catalogs of variable stars from the Quasar Equatorial Survey Team (QUEST; Vivas+ 2004, J/AJ/127/1158 ; Mateu+ 2012, J/MNRAS/427/3374 ; Zinn+ 2014, J/ApJ/781/22), Northern Sky Variability Survey (NSVS; Kinemuchi+ 2006, J/AJ/132/1202 ; Hoffman+ 2009, J/AJ/138/466), Lowell Observatory Near-Earth-Object Search (LONEOS; Miceli+ 2008, J/ApJ/678/865), General Catalogue of Variable Stars (GCVS; Samus+ 2009, J/PASP/121/1378), the Lincoln Near-Earth Asteroid Research (LINEAR; Sesar+ 2013, J/AJ/146/21) and the Catalina (Drake+ 2013, J/ApJ/765/154 & 2014, J/ApJS/213/9) surveys. See Section 2.1.

In the current work, our major spectroscopic data set comes from the LAMOST Galactic spectroscopic surveys (Deng+ 2012RAA....12..735D ; Zhao+ 2012RAA....12..723Z ; Liu+ 2014IAUS..298..310L). The spectra cover the wavelength range from 3700 to 9100Å with a resolving power R~1800. Another main source of spectra comes from the Sloan Digital Sky Surey (SDSS)/Sloan Extension for Galactic Understanding and Exploration (SEGUE; Yanny+ 2009, J/AJ/137/4377). All the data from SEGUE and SEGUE-II are included in SDSS Data Release 12 (SDSS DR12; Alam+ 2015, V/147). By combining the two data sets, a total of 6268 RRLs with a total of 31439 single-exposure spectra are obtained. Typical S/Ns of those single-exposure spectra are around 15.
