This is the distribution for OASYS of:
X-ray Refractive Optics Library for Physical Optics (formerly know as barc4ro)
This library allows simulating compound refractive lenses under the projection approximation, valid for the conditions imposed by the paraxial approximation in the physical optics framework.
