    Martins the IOD format allows for reporting in Az/el, use format codes
    4 ,5, 6 in column 46 . If you do want to convert, any planetarium programme
    which shows both Az/el and RA/Dec of mouse pointer will do, or you can
    look up the spherical trig formula and make a spread sheet do the work.
