Curve measured on the manufactured 0.5mm sample (not the nominal 2mm-equivalent basis used for the grade name), so absolute transmittance values on the plotted curve run higher than the 2mm-equivalent average-transmittance figures in the technical index table. Chromaticity data not published for this grade. Re-digitized against the clean sequential-page scan; curve reads genuinely ~0% from 200-280nm (UV cutoff) rising to ~59% at the 2500nm right edge — both edges confirmed against actual pixel values.
