SPHERE: A contouring program for spherical data

Research output: Contribution to journalArticlepeer-review

Abstract

This paper describes a method for displaying a sample of spherical data, by computing an "optimally" smoothed estimate of the underlying distribution and making a stereographic projection of the contours of this estimate. An interactive FORTRAN program which applies this method is supplied and described and examples given of its use.
