## Description

Title of program: CNFIT Catalogue Id: AAXQ_v1_0 Nature of problem Many high energy physics experiments require fitting of particle tracks. In particular, one often has to (e.g. OPAL at LEP) fit a curve to a set of points (xi,yi,zi),i=1,...,N each of which is a function of two measured independent quantities. Versions of this program held in the CPC repository in Mendeley Data AAXQ_v1_0; CNFIT; 10.1016/0010-4655(87)90097-X This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
