4.5.1.1 Correction factor: Possibility 1
The assumption made here is that somehow an error is introduced in Eq. 4.1 only and that
only this needs to be corrected for. This implies that (vertical line 1, Figure 4.16):

4.5.1.2 Correction factor: Possibility 2
Now the assumption is made that an error is introduced in Eq. 4.2 only and that only this
needs to be corrected for. This implies that (vertical line 2, Figure 4.16)
