Physics-Ellipsometry-VASE-0.02

Changes for version 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)
