    Well Rob, this is an ephemeris which is obviously meant to be used
    for historical research as the validity period is 1600 to 2100.
    Astronomers at the start of that era would certainly recognize this
    format for ecliptic longitudes, which is still used by astrologers
    today, as you correctly say. And today, astrologers do not have much
    use for ecliptic latitudes (they never did) and most astrologers
    would probably not know a Right Ascension if it hit them between the
    eyes. Right Ascension today is (I think) only used by astronomers. I
    would conclude that this is actually an astronomical almanac,
    formatted to be useful for historical research.
    
    As for it being as astrological website, I struggle to actually find
    the word "astrology" anywhere on the website!
