Detailed Description

Exponential/Sech^2 disk mixture model in flux^n or flux*color^{n-1} space.

The star formation history is constant and the same for all components in the mixture. A more general model is PopModelCacheSF which allows an arbitrary specification of an SF rate basis at the expense of additional storage.
