Design and evaluation of a white-LED ring for uniform CCD flat-field and contamination monitoring in HARPS3
The High Accuracy Radial velocity Planet Searcher 3 (HARPS3) is being developed for the Terra Hunting Experiment, a 10-year programme of nightly observations of solar-like stars to search for long-period, low-mass exoplanets. Reaching extreme-precision radial velocities (EPRV) at the 10 cm s−1 level requires every inst...
