We produce a new photometric calibration for the combined six-filter system formed by $Gaia$ DR2 + EDR3 G+GBP+GRP using an improved STIS/HST spectrophotometric library with very red stars. The comparison between observed and synthetic photometry yields residual dispersions of just 3.4-8.7 mmag, resulting in the most accurate and precise whole-sky large-dynamic-range optical photometric system ever obtained. We include some tests and applications.
