Revision history for Physics-Ellipsometry-VASE

0.02    2026-04-03
        - Auto-detect and parse J.A. Woollam VASE instrument files
        - Weighted fitting using measured sigma columns from Woollam data
        - Multi-angle color-coded plotting via PDL::Graphics::Gnuplot
        - Relative-step finite differences for numerical Jacobian
        - Store covariance matrix, iteration count, and model values after fit
        - Added Woollam format tests (t/03-woollam.t)
        - Added examples: Cauchy thin-film model, Tauc-Lorentz oscillator
        - Full POD documentation
        - CPAN packaging (MANIFEST, MANIFEST.SKIP, LICENSE)
