8 variables in columns and 661 lines for cored pedunculate oaks 1. Patch : a letter is the name of each of the 15 forest stands 2. Tree : tree name. Example : K_001_A means K = stand, 001 = tree number in this stand, A = name of the cored stem when a tree was multi-stemmed 3. TreeAge : tree age from seed; this age was inferred from dendrochronology information 4. FirstYear : year of the oldest tree-ring on the core (pith) 5. LastYear : year of the last tree-ring on the core (under bark) 6. DBHStem : diameter at breast height of the cored stem (cm) 7. DBHTree : diameter at breast height of the tree calculated from measurement of the circumference with a forest tape (in cm). DBHTree = DBHStem when the tree had only one stem, if not DBHTree > DBHStem 8. Corrector = BATree/BaStem. This ratio allows to correct the growth for multi-stemmed trees. We cored only stem per tree but the wood was produced in all the stems. Therefore, corrected BAI = BAI * corrector. Corrected BA and BAI are labelled BAc and BAIc in the file TreeRingData.txt. In the case of trees with only one stem, corrector = 1, then BA = BAc and BAI = BAIc
