Note: $^a$ First Overtone Blue Edge; $^b$ Fundamental Blue Edge; $^c$~First Overtone Red Edge; $^d$~Fundamental Red Edge. If no value is given at FOBE
and FORE, we found only fundamental models. A helium abundance
$Y$~= 0.24 and a mixing-length parameter $l/H_{\rm p}$~= 1.5 has been adopted.
Mass and luminosity are in solar units.
