+===== Physics ======
+^Code | Garstec (A- Wess rev., 2015)|||||
+^Convection| MLT, alpha = 1.801|||||
+^Overshoot | diffusion equation with exponential decay (Herwig type), including geometric limit applied to small convective cores (H_p towards the center makes overshoot regions too large). Proportion factor f = 0.02 (equivalent to  0.2 - 0.25 Hp in tradicional formulation) |||||
+^Extra mixing | Under the convective envelope (Vandenberg et al. 2012) as a function of its mass. Free parameters calibration forced to reproduce the solar Li and chemical abundances observed in globular clusters (e.g. Korn et al. en NGC 6397).|||||
+^gradT | Temperature gradient in overshoot regions is radiative.|||||
+^Wind | 1e-13 Msun / yr to avoid depletion of He and metals (included in extra missing calibration) |||||
+^Atmosphere | Eddington T-tau |||||
+^Nuclear rates | Adelberger et al. 2011, which includes de "low" value of LUNA's N14+p |||||
+^Screening | Weak (Salpeter)/intermediate (Graboske et al. 1973, subgiants) |||||
+^EOS |FreeEOS de Irwin |||||
+^Opacities | OPAL + Ferguson 2005 for low temperatures |||||
