I have libtoolised SOFA: <https://github.com/marcomaggi/atsofa> <http://code.google.com/p/libtoolisations/downloads/list> but the single test file I have included fails!!! Or I am understanding nothing... which is also possible. According to calculators on the Net, the Julian day number for 2013/01/13 is 2456306; but the function "iauCal2jd()" gives me 2455939.5. Damn! Damn! Damn! Time to lunch. -- Marco Maggi _________________________ Racket Developers list: http://lists.racket-lang.org/dev
