    Re: UL vs LL: which is which when an artificial horizon is involved?
    From: Tony Oz

    Dear Brad,

    You have really helped me a lot!! :)

    My "findings" about AH and limbs are:

    • there are only same-name limbs to touch (either UL to UL or LL to LL), a contrary-name limbs' touch gives an overlap;
    • the HS correction logic is the same - SD correction goes exactly as with the natural horizon (if LL - add SD; if UL - subtract SD)

    Today's Moon is perfect for such lessons. My previous confugion was because I was sighting always feature-less Sun.

    BTW, I am shocked to discover how warped (cosmetics box's) mirrors are! No surprise women are constantly discontent with their looks!... :)

    Thank you again!

    Warm regards,
    Tony
