Nearly done. One problem remaining, there is a ~3% difference in power between the old and the new implementation, non-constant over time and frequency. For the moment, it seems most definitely to be after time-bin selection. The scaling does not seem to influence the discrepancy.

When all scaling-operations have been removed, the differences are still there. All wavelets are exactly identical between the approaches. Still searching for the origin.

Ah, it turns out the difference is created because the new implementation shifted the time-bins 1 bin the right.
