This present paper sets out to perform a limited comparison between that method of P2P (point to point) scanning for Hypocenters, which uses the structure, imparted by a conformal mapping, to accelerate its ray tracing activity, and a method of scanning which incorporates the Earth spheroidal geometry directly within its ray tracing technique and which does not currently use a conformal mapping technique. The "conformal" method uses a mean-radius spherical Earth or can take a mean radius over

Depending on the function, the expected indication may be either a minimum or a maximum, occurring within the range of the response.
