The impact of interpolation in high-resolution spectroscopy -- The overlooked role of interpolation in radial velocity extraction
A. M. Silva, D. Doshi, K. Al Moulla +11
We explore the impact of spectral interpolation in radial velocity (RV) time-series extracted through template-based methods. We build synthetic datasets with Gaussian profiles to…

A systematic bias in template-based RV extraction algorithms
André M. Silva, N. C. Santos, J. P. Faria +30
In this paper we identify and explore a previously unidentified, multi meter-per-second, systematic correlation between time and RVs inferred through TM and LBL methods. We evaluat…

Catalog for the ESPRESSO blind radial velocity exoplanet survey
S. Hojjatpanah, P. Figueira, N. C. Santos +19
One of the main scientific drivers for ESPRESSO,Échelle SPectrograph, is the detection and characterization of Earth-class exoplanets. With this goal in mind, the ESPRESSO Guarante…
