Interactive Tauc plot evaluator

This app lets you interactively modify the fitting parameters used by the Tauc-fitting algorithm in the uvvistauc package,
making it easier to evaluate how the calculated band gap changes with changes to the fit parameters.

Step 1: please upload your spectrum (only OceanOptics TXT/ASCII file or CSV file with XY columns are supported).

Download an example spectrum (if you don't have one of your own)

Step 2: adjust your parameters, then click the button to see the Tauc plot and its algorithm visualised.
