This is a small correction to Equation (110) in [1]. Many thanks to Vincent Tan for discovering the error.

Erroneous statement

The erroneous statement is in Eq. (100), where I claimed that P12(y)P0(y)dy=exp(x12/σ2).

Fixing the error

The correct statement is P12(y)P0(y)dy=exp(+x12/σ2). Fortunately, this has no incidence on the rest of the paper, since we only cared about P12(y)P0(y)dy<.
