# Erratum: Null Geodesics Around a Kerr Black Hole

24-Apr-1998:
Someone recently pointed out to me a typo in the equations for
r_{H} and r_{stat}.
These are equations (2.11) and (2.12) on page 11 in
the PostScript version.
In
the hypertext version
they don't have numbers; they are found on the
hypertext document that has the following two addresses
http://www.astro.ku.dk/RelViz/milvang/000_node12.html
http://www.astro.ku.dk/~milvang/RelViz/000_node12.html

The first M^{2} should just be an M,
like in the equation for r_{H} which also
includes the natural constants G and c (the equation just below the two
above-mentioned, which is Eq. 2.13 in the PostScript version).
