Dear Alex, thank you very much for bringing my attention to those formulas! Looks like they are the key to understand the way how to build the Weem's Star Altitude Curves (my recent topic of interest).
Now, having looked at the problem, I think the difficulties you at times hit are because for some certain Bx values the curve has two points with the same LHA but different Lat. I do not know how to deal with this (yet).
