Detailed Description

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

The star formation history is specified in SF rate basis in a file named basis.data.

A constant fixed birth rate model is used to for the confusion computation. This model is the same as in PopModelCacheF.

The format for basis.data is as follows: the first line is an integer specifying the number of members of the basis, the second line is the number of temporal bins and this must match the input isochrone data, basis members are speficied in each successive line as a row of weights for each temporal bin.
