SDSS, DES, and LSST Synthetic Magnitudes derived from Gaia XP Spectra

Gaia XP synthetic photometry - data release for validation samples This release contains synthetic ugrizy photometry (SDSS, DES/DECam, and LSST systems) and the underlying extended spectra, derived from Gaia DR3 XP continuous spectra, for three validation samples (Stripe 82, DES, LSST DP1). This release accompanies the paper `Vera C. Rubin LSST Synthetic Magnitudes derived from Gaia XP Spectra` by O. Razim, K. Tisanic, and L. Palaversa (submitted to A&A). The code for reproducing the results, together with demo notebooks for this catalogs usage, is available in [the repository](https://github.com/ShrRa/LSST_Gaia_XPy_public).
