An HP PPL implementation of the IAU 2000b nutation algorithm

Updated on December 1, 2022

This version allows the user to specify how many rows of tabular data are used in the nutation computations. This can be done on line 20 of the source code using the following syntax.

// number of rows of data to use in calculation (1 <= nrows <= 78)

EXPORT nrows := 78;

A low-precision nutation version typically uses the first 13 rows of data (nrows := 13).

This version is available at the same download link as the original.
