Reconstructed inclination angle along the leaf axis. Plot a shows the inclination angle \({i}_{c}\) (Ref) and \({i}_{r}\) (Rec) along the leaf axis \(X\). Plot b shows the difference between \({i}_{c}\) and \({i}_{r}\). The difference between \({i}_{r}\) and \({i}_{c}\) \(\Delta \left({i}_{c},{i}_{r}\right)\) varies between − 6° and 4°. Mean error (ME) and standard deviation σ for \(\Delta ({i}_{c},{i}_{r})\) for the four reconstructions (Rec_n) were: Rec₁: ME = − 0.43°, σ = 2.38; Rec₂: ME = 0.37°, σ = 1.22°; Rec₃: ME = 0.73°, σ = 0.68; Rec₄: ME = 0.51, σ = 1.05
