    NA: the combined effects of parallax and refraction?
    From: Tony Oz

    Dear Frank,

    Your LUNARS ARE EASY article advises to look for dh_Moon and dh_Sun, which are...

    ...the combined effects of parallax and refraction. And here we can use the standard tables in the Nautical Almanac. Opening the front cover of the Nautical Almanac...

    Apparently these tables are not available in the Air Almanac (if I'm not mistaken). Are those table available as a stand-alone document? Where can one obtain them?

    Thank you in advance.

    Warm regards,
    Tony
