* Sellmeier formula is derived by the authors of ref. 1 using their own data in the 0.1404-0.2537 μm range combined with data from ref. 2 at longer wavelengths.
** A misprint is corrected in the Sellmeier formula: "182.90" is replaced by "1.8290" in the nominator of the second term before converting the formula to the form used in the refractiveindex.info database.
