......@@ -31,7 +31,7 @@ From the man page of the pow-function:
- The pow() function returns the value of x raised to the power of y.
- If y is 0, the result is 1.0 (even if x is a NaN).
We potentially face two problems:
We potentially face three problems:
1 When using the zero offset (least offset) trace as a reference for offset
dependent scaling (as is the default), a division by zero happens in
subroutine mpcfactors.

the latter step there happens the nasty division by zero (division by mpc
factor). This problem is present, even is the zero offset trace is not used
as a reference.
3 For a negative exponent the mpc factor of the zero offset trace would become
infinite even for a finite reference value.
Solutions:
1 The first problem is resolved by not using a zero-offset trace as a
