Erratum: Null Geodesics Around a Kerr Black Hole

24-Apr-1998: Someone recently pointed out to me a typo in the equations for rH and rstat. 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
The first M2 should just be an M, like in the equation for rH 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).
