Photometric transformations between Gaia DR3 and the Johnson–Cousins system (Python implementation)
Abstract
This repository contains the Python notebook TransformacionGaia_LandoltFinal.ipynb, developed to derive and evaluate photometric transformations between the Gaia DR3 broad bands (G, GBP, GRP) and the classical Johnson–Cousins photometric system (U, B, V, R, I). The notebook includes the cross-matched Landolt standard star sample, the fitting of transformation equations, the analysis of residuals, and the comparative bewteen Riello transformations.
