cds-question@unistra.frvariable-starsradial-velocityWe present template radial velocity curves of ab-type RR Lyrae stars constructed from high-precision measurements of H{alpha}, H{beta}, and H{gamma} lines. Amplitude correlations between the Balmer line velocity curves, Johnson V band, and Sloan Digital Sky Survey (SDSS) g- and r-band light curves are also derived. Compared to previous methods, these templates and derived correlations reduce the uncertainty in measured systemic (center-of-mass) velocities of RR Lyrae stars by up to 15km/s, and will be of particular interest to wide-area spectroscopic surveys such as the SDSS and LAMOST Experiment for Galactic Understanding and Exploration.2012AJ....144..114Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/144/114CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/194/38 : Radial velocities of 11 field RR Lyrae (For+, 2011)J/ApJ/708/717 : Light curve templates of RR Lyrae stars (Sesar+, 2010)J/MNRAS/377/1263 : Multiperiodic RR Lyrae in ASAS catalog (Szczygiel+, 2007)J/A+AS/125/321 : RR Lyrae radial velocities and [Fe/H] II.
