HIRES Precision RV Pipeline v 1.0 Release (Nov. 19, 2018)

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. The processing environment runs on servers at NExScI and is accessible through python web services calls, which the user runs on their own client-side machines. The precision radial velocity code is not available to download and is otherwise not visible to the users. To use this service, a user must have PI HIRES data in the Keck Observatory Archive (KOA) that were taken in the proper configuration and a user must install a small python package on their location machine. The python package is utilized to log on to the service, download data from the archive to the server-side processing environment, invoke the reduction and processing of the data, and extract the precision radial velocity results.
