Understanding the purpose of modelling parameters...

Effective Source Size parameters -> penumbra
Rounded leaf end radius –> raytraced attenuation -> penumbra
Energy spectrum -> depth doses
Electron contamination parameters -> buildup part of depth doses
Infield parameters -> open beam fluence profile
Spectral off-axis softening -> attenuation variation off-axis
Interleaf leakage –> “wiggling” in out-of-field profiles
Transmission factors -> “bottom” part of out-of-field profiles
Flattening Filter Scatter Source -> output factor & out of field profile
Manual parameter tuning <-> Automodeling ?
