Notes

* Bédard et al. (2020)

** Buchan et al. (2025). Specifically, the diffusion timescales provided here are those from the so-called SV grid, which includes convective overshoot following a 1D parameterization where the extent of the overshoot region varies with effective temperature. See Section 4.2 of the paper for details.
