An Inverse of the Circular Coverage Function

Abstract

This report describes an algorithm, INCIR, to evaluate an inverse of the Circular Coverage Function, CIR. Given a two-dimensional normal distribution function with mean zero and equal unit standard deviations and a target located at (h, k); R, the radius of the circle, C, with center at (h, k) is determined for a specified probability of a shot falling within C. A Fortran 77 subroutine, INVCIR, is available that is based on INCIR, which produces R to eight significant digits for 10(exp -8) less than or equal to P less than or equal to 1 - 10(exp -8) and 0 less than or equal to d = (h(exp 2) + k(exp 2))1/2 less than or equal to 10(exp 8). The appendix contains a 22-page table that shows the tabulation of R as a function of P and d.
