The included BaSTI isochrones appear to have values of -99 for most of the isochrone logG values (see e.g. isoc_z0.0200.dat). Only the added on remnant populations do not have this value. I was curious because the BaSTI website (old and new) also do not provide logG at all, and since it also does not provide a stellar radius I don't see how you can compute it from the isochrones directly.
Looking through the FSPS code I cannot see an obvious answer to how it works round this limitation when it comes to interpolating spectra onto the isochrone grid. Could somebody perhaps explain or point me in the right direction (or is this actually a bug?)
