Dartmouth Isochrones with C+N+O vs. [Fe/H] relation for Omega Centauri

The updated_dotter_isochrones.zip file includes two subdirectories: HST_ACSWF and HST_WFC3, each of which contain the isochrones models modeled after the respective filter bandpasses. With each subdirectory there are 24 files, each schematically labeled to describe the metallicity, alpha abundance, and helium abundance of the given model. Models labeled with "_y40" are helium enhanced while files lacking this suffix are models with primordial helium abundance. More information can be found in the header of each file. These model grids are used in conjunction with the interpolation tools at the Dartmouth Stellar Evolution Database: https://stellar.dartmouth.edu/ to generate the files we use in our analysis.
