    Took your coefficients, edited them to provide tab separators, and copied
    them onto an Excel spreadsheet. Then used the coefficients to evaluate the
    GHA and dec of the Sept sun from day 1 to day 30, all at 0000. Worst error
    I found was on Sept 1 where the coefficients gave a dec of 8d 15.8m N, the
    Nautical Alamanac gives 8d 15.4m N. Other values were mostly within 1
    minute, a few had an error of 2 minutes.
    I think you have a useful tool.
