VizieR Online Data Catalog: GJ 4276 radial velocity curve (Nagel+, 2019)

We analyzed radial velocity data from the CARMENES VIS channel. The RVs are corrected for barycentric motion and secular acceleration. The CARMENES measurements were taken in the context of the CARMENES search for exoplanets around M dwarfs. The CARMENES instrument consists of two channels: the VIS channel obtains spectra at a resolution of R=94600 in the wavelength range 520-960nm, while the NIR channel yields spectra of R=80400 covering 960-1710nm. Both channels are calibrated in wavelength with hollow-cathode lamps and use temperature- and pressure-stabilized Fabry-Perot etalons to interpolate the wavelength solution and simultaneously monitor the spectrograph drift during nightly operations (Bauer et al., 2015A&A...581A.117B).

To determine the stellar rotation period, we obtained V band photometry with the T150 telescope located at the Sierra Nevada Observatory (SNO) in Spain.
