Here's a cool website that talks some of the variables you mentioned. It looks like n_d is the index refraction and v-no is the abbe number, where abbe is the reciprocal dispersion of a transparent material. https://www.pencilofrays.com/double-gauss-sonnar-comparison/
What are nd and V-no in this table?
