    That sounds right. I convert positions from ascension,
    declination and distance into galactic rectangular coordinates
    with origo at the sun and the Z axis up from the plane.

    I like playing around with datasets like this, there is so much
    to find. Not to mention where to go later - I really want to
    check out the Orion complex and the nebulas of the Sagittarius
    arm in person.
