uncertainty contributors in calibration measurements,
especially for thin film devices, and the most complex to
calculate analytically due to underlying correlations in
uncertainty. Typically, empirical estimates or Monte
Carlo simulations based on wavelength dependent
uncertainty analysis are used and sampling is conducted
by random walks. A different sampling approach is
proposed based on fitting a sum of Gaussian
distributions to measurement data and generating
spectral response curves within the uncertainty envelope
by altering the fitting parameters. The generated curves
are smooth and approximate real measurement data.
Presently, the sampling method is limited to SRs.
