VizieR Online Data Catalog: Classical Cepheids consistent radial velocities (Borgniet+, 2019)
Résumé
Our sample is made up of 64 Classical Galactic Cepheids with pulsation periods in the range 2 to 68 days. We provide the full details of our sample in Table A.1. We present both the six correlation templates built to derive tailored cross-correlation functions (CCFs), the CCFs themselves, and the derived radial velocity and line profile observable time series. All data are provided with the corresponding Cepheid name, the spectrograph used to observe the target, the Modified Julian Day (MJD) of the observation and the observation program identifier. The data are provided over three different wavelength ranges: "blue" from 390 to 498nm; "green" from 450 to 680nm; and "red" from 570 to 880nm, corresponding to the letters "b", "g", and "r" (first identifier within the file names). Depending on this range, the data are computed based on one (for the "blue" and "red" ranges) or four (for the "green" range) different correlation templates, corresponding to different sets of spectral lines selected based on their relative depth: weak, medium, deep and all lines. The corresponding identifiers are the letters "w", "m", "d", and "a" (second identifier within the file names). Finally, the radial velocities and other line profile observables are computed in three different ways for each star, each spectrograph, each wavelength range, and each template: first based on the CCF first moment or centroid, second based on a Gaussian fit of the CCF, and third based on a BiGaussian fit of the CCF. The corresponding identifiers are the letters "c", "g" and "b" (third identifier within the rv file names). (28 data files).
