The best fit MIST and PARSEC model isochrones to the full population, the main sequence only, and pre-main sequence only population, respectively. The absolute magnitude M_G is based on the EDR3 parallax. It is clear that the isochrones that was fitted to the pre-main sequence only miss the fit due to the absence of the constraint from the MS stars, resulting in inconsistent extinction, regardless of models. Of the 4 remaining isochrones, the range in the age is between 3.8 Myr and 4.8 Myr and the A_V that was determined is around 1.5–1.7 for all models, consistent with the literature values.
