The radial velocity fitting challenge. II. First results of the analysis of the data set

Radial velocimetry has become an essential method for the discovery and characterization of exoplanets. However, its efficiency and reliability have remain unclear for small signals (i.e., small-mass planets, or planets on long-period orbits). This paper shows the results of a blind test run by eight different teams. The analysis of these results will be crucial in determining the reliability of the detections and can be used to improve detection algorithms.
