A Modified Gooding Method to Calculate Inclination Functions

In this paper, the expression of V klm(I) in the Gooding method is rewritten to be the form convenient for calculation, and a standard recursive lm procedure is used to calculate Aklm(I). We have rewritten the Goodingʹs program under the assumption that l and k have the same odd-even parity, this makes the program be shorten for one half, the computational effciency and readability of the program be raised, the computing time be shortened for 41%, and the computational accuracy and stability are also slightly improved.
