Fig. 2.

The RCS curves that were used for standardisation. Red line is the mean MXD by ring age, and black line is the count-weighted mean of the smoothed RCS curves. The two individual RCS curves, smoothed with age dependant spline, used for trees with higher and lower mean MXD are shown as grey and brown lines. The grey area shows mean-tree sample depth.
