RIXExpansion: Refractive Index nD (Liquid)

nD = å Bi ×ti + å Cj ×wj ; the summations are from i = 0 to (nTerms - 1) and j = 1 to nTerms.

t = T - 298.15 K and w = WL - 589.26 (WL = wavelength in nm)

Evaluation Results:
annotated evaluation results showing constant parameter: nTerms [here 2] and fitted parameters (top to bottom):B_0, B_1, C_1, C_2
