Significant Digit Computation of the Elliptical Coverage Function

Abstract

An algorithm is given for evaluating the elliptical coverage function. A fortran subroutine PKILL supplies the function to at least six significant digits over a large range of the input parameters when the precision is not restricted by inherent error. Several new procedures are used. An algorithm is also given for the supporting function erf(x + h) - erf(x - h). A fortran function AERF supplies this function to 12 significant digits. Listings of transportable Fortran subprograms PKILL and AERF are included.
