The Gaia BP/RP spectra package.

Get Started

About the package

BP/RP spectra became available for the first time in Gaia Data Release 3 (DR3). In their first release, only source mean spectra are available: these are spectra that have been generated from a number of single observations of the same object. Epoch spectra, i.e. spectra consisting of one single observation, will become available in future releases.

GaiaXPy is a Python library to facilitate handling Gaia BP/RP spectra as distributed from the Gaia archive.
