A Comment on Black Hole Entropy in String Theory

TL;DR
The string-theoretic calculation of black hole entropy is extended, first performed by Susskind and Uglum, and it is shown that the result agrees with that obtained from the classical action of string theory, using the Noether charge method developed by Wald.
Abstract
In this note, we extend the string theoretic calculation of the black hole entropy, first performed by Susskind and Uglum, away from the infinite mass limit. It is shown that the result agrees with that obtained from the classical action of string theory, using the Noether charge method developed by Wald. Also shown in the process is the equivalence of two general techniques for finding black hole entropies-the Noether charge method, and the method of conical singularities.
