KOA Table Access Protocol (TAP) Client

Version 1 of PyKOA offers access to public raw science and calibration files acquired with the HIRES echelle-spectrograph, and for Keck Observatory PIs, secure access to their protected data with the KOA credentials already assigned to them. The remaining Keck instruments are expected to be available before the end of 2020. Queries made through PyKOA are underpinned by nexsciTAP, a NExScI Python-based server that implements the IVOA Table Access Protocol (TAP). This design enables a rich variety of searches, including cone, box, polygon, or all-sky spatial searches; temporal searches; searches on program infortmation; and complex searches on multiple attributes.

The Keck Observatory Archive (KOA) is a collaboration between the NASA Exoplanet Science Institute (NExScI) and the W. M. Keck Observatory (WMKO). NExScI is sponsored by NASA’s Exoplanet Exploration Program, and operated by the California Institute of Technology in coordination with the Jet Propulsion Laboratory (JPL).
