Isochrone Interpolation


06/19/18: We've temporarily rolled back to v1.1 while we iron out some remaining issues with v1.2. Please check back in a day or two! We apologize for the inconvenience.

NOTE: [Fe/H]=[Z/H] for v1.1 since all models have solar-scaled abundances. This represents the initial bulk metallicity, computed assuming the Asplund et al. 2009 protosolar abundances where Z=0.0142.
[Fe/H] = (-4 ≤ [Fe/H] ≤ +0.5)

Output Options

NOTE: All synthetic photometry files include the following columns: #EEP, age, initial mass, logTeff, logg, logL, and surface Z. See README_TABLES for more details about the available columns. The zero points depend on the photometric system—check the file headers for details.
