Average attenuation template: scaling factor as a fitable parameter? about dust_attenuation

[karllark]

Giving this more thought, I think A(V) should be a fittable parameter.
The reason is the for the most correct attenuation models - the ones based on radiative transfer results - A(V) has to be a parameter as the shape is dependent on A(V). While this is not true for the average models like Calzetti00, I think it would be best to have as similar interface as possible between the models.

I agree, and that's good as this is already what C00 and WG00 are doing.

Great. We'll stay with what we are doing. :-)
