aberrations

Aberrations Package

Provides the Aberrations facade and focused sub-classes for computing first- and third-order aberrations.

The public Aberrations class delegates to three focused classes:

ThirdOrderAberrations (TSC, SC, CC, TCC, TAC, AC, TPC, PC, DC)
SeidelAberrations (seidels)
ChromaticAberrations (TAchC, LchC, TchC)

All public methods on Aberrations continue to work unchanged.
