Abstract The program SPHAN estimates the spherical harmonic coefficients of a scalar field by least-square fitting of data values measured on an equal angular grid on a globe. Title of program: SPHAN Catalogue Id: ABTU_v1_0 Nature of problem There is a wide range of applications of spherical harmonic analysis of regularly spaced data in reduction of global data set to spherical harmonic coefficients. Versions of this program held in the CPC repository in Mendeley Data ABTU_v1_0; SPHAN; 10.1016/0010-4655(91)90057-R This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2018)
