In what follows, we correct the errors that appeared in .
The integrals in Eqs. (6) and (20) are each missing a normalization factor of
. Equation (6) should read and Eq. (20) should read
The second and third diagonal entries of the matrix given in Eq. (16) are incorrect. The correct
result for is
The second term in the definition of given in Eq. (18) contains several errors: there
is a missing scalar factor of 2, and the (2, 2), (2, 3), and (3, 2) entries are
incorrect. The correct definition of is
As a consequence of the errata in Eq. (18), which are addressed above,
Eqs. (23) and (24) have errors. The corrected equations are
In these corrected equations, we have introduced for , 2.
