XLSTEM calculates the following information from ring width data produced by WinDENDRO:

• Mean radius (quadratic method), diameter and area per disk (available cumulatively or incrementally).
• Tree height and volume as a function of age or year (available cumulatively or incrementally).
• Basal and summary information about the tree.

Three height interpolation methods are provided:

• Linear
• Carmean
• Newberry

Calculations can be done interactively on selected trees or in batch.

All data can be displayed graphically.
