QSM Allometric Correction
Plugin : SimpleForestNom de classe : SF_StepQSMAllometricCorrection
Description
In Hackenberg et al 2023 we describe input and output parameters of an allometric correction function.

Allometric correction:
With this version you need to execute QSM Detect Wellfit Cylinders before.:
For full models without removed twigs due to leave removal filter I recommend now parabolic taper fit. But this one does not support automatic estimate average radius and always forces intercept zero while fitting the taper function.
If the fitted radius is smaller than 1/ [correction range] times the predicted radius, it is corrected.
If the fitted radius is larger than [correction range] times the predicted radius, it is corrected.

- The lower the [correction range] , a number larger 1, the more strict is the check: 1.500 . .
If the fitted radius is smaller than 1/ [correction range] times the predicted radius, it is corrected.
If the fitted radius is larger than [correction range] times the predicted radius, it is corrected.
- If twigs were removed during denoising automatically [estimate average radius] Désactivé . .
