LEGCK, A SUBROUTINE TO ANALYZE LEGENDRE COEFFICIENTS FOR NEGATIVITY IN THE ANGULAR DISTRIBUTION.

Abstract

LEGCK is a subroutine package designed to analyze Legendre expansions of angular distributions for negative regions. The analysis is divided into two portions. The first check determines if the Legendre coefficients are 'possible', that is, if any negativity is due only to the truncation of the Legendre expansion. The second test determines if there are regions of negativity in the truncated expansion and where such negative regions are. The report describes the subroutines in the package and discusses the operations performed by each subroutine. (Author)
