VizieR Online Data Catalog: Radial velocities of magnetic Ap stars (Mathys, 2017)
Abstract
Radial velocities measured at multiple epochs for 43 Ap stars with resolved magnetically split lines, from observations of Mathys (1991A&AS...89..121M), Mathys et al. (1997, Cat. J/A+AS/123/353), Mathys & Hubrig (1997A&AS..124..475M), and the present paper. As described in the latter, the adopted value for the measurements uncertainties is 2km/s for those based on spectra recorded in circular polarisation with the ESO CASPEC spectrograph, and 1km/s for all other determinations, from high-resolution spectra recorded in natural light with various combinations of telescopes and instruments.
