    Margetts curves for lunar clearance
    From: Francis Upchurch

    A question maybe for Frank and Ken Muldrew? I've at last got round to looking at these wonderful graphs/curves from 1790. (thanks to Frank and Ken for earlier posts on this.) Do you happen to know the original dimensions? I've re-looked at some posts from Frank and Ken over the years. Very interesting. I'm probably going to have a go at printing out the whole thing, but would appreciate advice on dimensions required for the 4" accuracy cited. Ken, are you still clearing lunars with these? If so, do you consistently get that sort of accuracy?

    Best wishes

    Francis
