Glazing data redistributed with cdfoley.com =========================================== This folder holds files copied byte for byte from two open-source projects of Lawrence Berkeley National Laboratory (LBNL). Nothing in them has been changed. The cdfoley.com glazing calculator reads them in the visitor's browser, resamples the spectra to its own 5 nm wavelength grid for each calculation, and shows only computed results. SHA-256 hashes of every file are listed in ../manifest.json.
