David Thank You Very Much for Your help. I'm not familiar with "arc error" or the "Q or P in A". One of them must be Altitude: Semi-Diameter/Parallax tho I'm assuming that would be the arc error? The P being atmospheric pressure? I haven't even a guess for the Q or A. I am really trying to learn this the right way and am very glad to have your time and help. Your previous answer has already helped me greatly.
