Radial Velocity Challenge At The Aiuc

"PUCHEROS (2012, UC observatory) and FIDEOS (2016, ESO-1m La Silla Observatory), are optical echelle high-resolution spectrographs developed in the AIUC, Chile. A thorium-argon hollow-cathode emission-line lamp is used as wavelength calibration method in the two spectrographs. We show the results of the study in radial velocity stability of the instruments. Additionally, we identify the main factors that limit the performance of these spectrographs, and how we deal with them in order to achieve a better stability and precision in radial velocity measures."
