Abstract

We present the results of the ground-based observing campaign to build the grid of Spectro-Photometric Standard Stars (SPSS) for the absolute flux calibration of data gathered by Gaia, the European Space Agency (ESA) astrometric mission. The spectro-photometric standard stars catalog is characterized by an internal ≅1% accuracy (and sub-percent precision) and it is tied to the CALSPEC Vega and Sirius systems within ≅1%. The final list of SPSS and their flux tables are presented, together with all the quality parameters and associated stellar properties derived from Gaia and the literature. Improvements with respect to the previous SPSS release (Pancino et al. 2021) are discussed, concerning especially the flux accuracy in the red part of the spectrum, above 800 nm. The grid will be used to calibrate Gaia photometry and spectra fluxes in the DR4 and DR5 releases.
