Hertzsprung–Russell diagram for the IC 348 members included in the accretion analysis. The orange, blue, and red curves show the PARSEC, BHAC15, and ATMO2020 evolutionary models adopted in this work, respectively. Isochrones at 1, 2, and 10 Myr are shown, with the adopted 2 Myr isochrone emphasized. Stellar luminosities are calculated from the adopted effective temperatures and final evolutionary-model radii using the Stefan–Boltzmann relation.
