Curve measured on the manufactured 1mm sample (not the nominal 2mm-equivalent basis used for the grade name). Chromaticity data not published for this grade. Re-digitized against the clean sequential-page scan; curve reads genuinely ~0% from 200-320nm (UV cutoff) rising to ~20% at the 2500nm right edge.
