VizieR Online Data Catalog: FEROS, HARPS and HIRES radial velocity of HD33142 (Trifonov+, 2022)
Abstract
The Fiber-fed Extended Range Optical Spectrograph(FEROS) is an echelle spectrograph installed at the 2.2m Max Planck Gesellschaft (MPG/ESO) telescope at ESO's La Silla Observatory, Chile, and has a resolving power of R=48000. We obtained 27 spectra with FEROS from our survey and found one additional FEROS spectrum in the ESO archive which was taken on 2012 February 22.
The High Accuracy Radial velocity Planet Searcher (HARPS) is a precise cross-dispersed echelle spectrograph installed at the ESO 3.6m telescope at La Silla Observatory, Chile. It has a spectral resolution of R=115000 and reaches an RV measurement precision of ~1m/s. We obtained 88 high signal-to-noise spectra for HD33142 within our HARPS survey, and found 10 more HARPS spectra for this star in the ESO archive. The High Resolution Echelle Spectrometer (HIRES) is a grating cross-dispersed echelle spectrograph mounted on the KECK 10m telescope on Mauna Kea, Hawaii. It has a spectral resolving power of R=25000-85000, depending on the chosen slit and can reach a precision of ~3m/s when the highest resolution is used. We use 40 archival HIRES spectra taken from 2007 October to 2020 March corresponding to a temporal baseline of ~4500days. (3 data files).- Publication:
