    Re: Plumb-line horizon vs. geocentric horizon
    From: Charles Seitz

    I guess I'm about to get into trouble here
again but I'm now totally confused about
what a plumb line is in the context of the
discussion.  Is it a direction defined by a
plumb bob suspended from a cord or the
local vertical?
