As an alternative to downloading large sets of isochrones and the accompanying programs, the links on this page point to web interfaces to the most useful programs available in the Programs section.

Simply fill out the forms on the following pages, click the submit button, and soon links to the results will appear in your browser window.

Isochrones and Luminosity Functions (2012 Update)

Create isochrones for any [Fe/H] within the grid (-2.5 to +0.5) for any available [α/Fe], Y, and photometric system. The resulting isochrones can then be converted to luminosity functions built on any filter in the photometric system and either a Power-Law or Log-Normal IMF with user-supplied IMF parameters. Currently available only for the 1 - 15 Gyr isochrone set.


Synthetic Horizontal Branch Models

Create a synthetic horizontal branch (SHB) model for any [Fe/H] with the grid (-2.5 to +0.5) for any available [α/Fe] and photometric system. The SHB model is created from a number of randomly generated stars drawn from a Gaussian distribution with user-supplied parameters.
