Red noise versus planetary interpretations in the microlensing event OGLE-2013-BLG-446

E. Bachelet, D. M. Bramich, C. Han +98

For all exoplanet candidates, the reliability of a claimed detection needs to be assessed through a careful study of systematic errors in the data to minimize the false positives r…
