avg: The avg field shows the estimated van Genuchten (1989) a parameter.

 

nvg: The nvg field shows the estimated van Genuchten (1989) n parameter.

 

mvg: The mvg field shows the estimated van Genuchten (1989) m parameter.

 

Residual WC: The Residual WC refers to the calculated residual gravimetric water content according to the method proposed by van Genuchten (1989).

 

Predicted: The Predicted Field indicates if the estimation algorithm has been successfully executed on the current data.

 

Error: The Error field shows the difference between the fit and laboratory values in terms of R2.

 

AEV: The AEV field shows the air-entry value as calculated based on the estimated curve.

 

Max. Slope: The Max. Slope is the maximum slope (on a semi-log scale) as calculated based on the estimation curve.
