Isochrones and HB/AGB tracks can be manipulated using these Fortran programs.
The programs have been tested on Mac OS X and Linux using GNU compilers.
Isochrone [Fe/H]-Interpolation --- Try the Web Tools version!
iso_interp_feh.f allows interpolation in [Fe/H] at fixed [α/Fe], Y, and age. This version is compatible with the updated 2012 isochrones. An older version, compatible with the original isochrones, is available upon request.
Luminosity Functions --- Try the Web Tools version!
isolf.f transforms isochrones into Luminosity Functions (LFs; either lognormal or power law IMF) using any filter from any photometric system for which isochrones are available. Compatible with 2012 isochrones; older version available upon request.
Synthetic Horizontal Branch Models --- Try the Web Tools version!
shb.f along with a complete set of HB-AGB tracks can be used to generate synthetic horizontal branch models, including [Fe/H]-interpolation.
Isochrone or Luminosity Function File Separation
isolf_split.f separates one large file (either isochrones or luminosity functions) containing multiple ages into a number of individual files, one for each age.
