    Many thanks for the update of the references for astronomical algorithms. 
    I am very pleased to see the SOFA source code algorithms are freely available 
    on the internet as a common international resource. 
     
    It's a long time I played around with astro for amusement. Having taken up an 
    interest again as a hobby I shall have to brush up my 'C' programming on the 
    computer to try them for fun it, being the early 1990s when I last played 
    around with programming in 'C'.    I still use a calculator programmed from 
    the 'Explanatory Supplement' (1974 impression) and Meeus' book.
