Yes, it doesn't look like from Ageton' method, despite the fact that in that method A,B, C, R, K, L, H are used ( yes, in the table itself, just A,B, and K. Others are for the intermediate results.) I'm still inclined to believe that those are the sides and angles of a spherical triangle. Bowditch, Chapter 14. And, if it is for the sight reduction process, what else it could be, except for the well-known just few methods? The basis for all those is a spherical triangle and the sin and cos formulas to solving the sides and angles. Just my humble opinion.
