NExScI, in collaboration with Caltech and the Keck Observatory, is providing access to a processing environment suitable for producing precision radial velocities for HIRES data that have been acquired in a specific manner. Version 3.0 of the HIRES Precision Radial Velocity Processing environment provides access to a pre-reduced dataset containing all compatible public radial velocity observations collected with HIRES since 2004. Over 60,000 Radial Velocities for over 1600 stars have been processed with precision comparable to other state of the art reduction pipelines for HIRES data. This dataset will help scientists discover new planets, better characterize existing planets, and gain insight into stellar astrophysics.
