Re: [ATM] repeatable mounting of thin mirror

Wedge is best measured just in from the edge of the mirror rather than at
its real edge.  The Newport site has a nice article on a measuring device
for determining the amount of wedge in a piece of glass.  Others may have
put up their own versions of the tool and it is easy to build.
