    Ron,

    I have never before seen the sort of plotting sheet you attached to your post.  I presume the dashed lines at the bottom - which are rather like two piece of pie, facing each other point-to-point - help me determine the width of a degree of longitude.  But I can't quite picture how they are used.  Could you comment on this?

    The type of plotting sheet I am accustomed to is attached.  Yours is more visually interesting, to be sure.

    Thanks,

    Bob
