Comment:
Replying to [comment:15 dkrenn]:
> Code looks good. I didn't review the extension of
`_sa_coefficients_lambda_` directly (only indirectly, since the overall
results are correct). Git blame says Benjamin has done these changes;
Clemens, did you have a look at these changes?
Yes. The only difference is that `(1+1/v) * (1+v*t).log()` representing
the logarithm of the denominator `z^(n+1)` has been changed to
`(1+1/v+beta) * (1+v*t).log()` representing the logarithm of the
denominator `z^(n+1+beta)` where the additional factor `z^beta` comes from
the renormalization of the logarithmic factor.
> @Clemens: You should add yourself as author as well.
Done, thanks for the reminder.
