Important: Citing this work

If you use the results of this web form in a paper please remember that you are making use of two data products: EzGal, as well as the model set that you have chosen. These magnitude evolution calculations are only possible because someone else has gone through effort of generating stellar evolution models. So, I certainly appreciate an acknowledgement or citation for EzGal if you make use of it, but it is most important that you cite the paper which describes the model sets you are using. Here are the appropriate references:

All model calculations from this form are made using interpolated models. The default models have been interpolated onto a common metallicity grid to enable direct model comparisons. Also, all CSP models have been generated using EzGal to remove any differences caused by differing numeric techniques. The original, unmodified models for each model set are available on the download page in a EzGal-ready model format if you need them.
