As some of you may know, we have open sourced the physics code for CalcZAF on the OpenMicroAnalysis Google Group started by Philippe Pinard and Hendrix Demers.
Philippe did a nice job and, as I and others continue to update the code (new fluorescence correction coming soon with collaboration with Philippe Pinard and Karsten Goemann!), the Python script Philippe wrote will allow for a quick update of the CalcZAF Github project.
It looks pretty cool and one can easily browse the source code files easily as seen here:
