Hello. I am currently trying to calculate the equation of a hyperbola, which I have little experience with. The hyperbola has a "sphere radius" of 153mm and a "hyperbolic factor" of 21500. I haven't been able to find anything online about what these mean and am lost. The parameters where given to me by a program called optical ray tracer which is used to model light rays in 2D. I am currently designing a telescope's mirror.
