Attributes in entity 4: Growth-changes: Douglas-fir		Details
1. TAG Definition: Tree identification number Units: number Domain: range (minimum = 1101.  maximum = 3003.)
2. HEIGHT Definition: Height (relative to stump surface) from which sample was taken Units: meters Domain: range (minimum = -0.38  maximum = 0.00)
3. SAMPLE Definition: Identification (A-G, case insensitive) for sample taken from this tree (Tag) at this height (Height) Domain: freetext
4. EVENTTYPE Definition: Type of occurrence in tree-ring sample Domain: enum
5. EVENTYEAR Definition: Calendar year of event (Event type), as determined from tree rings Units: year (yyyy) Domain: range (minimum = 0.  maximum = 1991.)
6. DECADE Definition: Decade of event, calculated from Date and designated by 1st year of decade (e.g.1500 designates the decade 1500-1509) Units: year (yyyy) Domain: range (minimum = 0.  maximum = 1990.)
7. EVENTRAD Definition: Distance (cm) from the center of the sample to the tree-ring at which the event occurs (or begins). Units: centimeters Domain: range (minimum = 0.0  maximum = 77.0)
8. AGEOFEVENT Definition: Calculated from Date of event (Event type = C, R, or S), minus Date of center. Units: number of years Domain: range (minimum = 0.  maximum = 486.)
9. SIZOFEVENT Definition: For event types R and S, this is a measure of the size of the growth-change, and is evaluated as a ratio: (width of 10 rings following Date) / (width of 10 rings preceeding Date). For event type C, this attribute is left blank. Units: number Domain: range (minimum = 0.25  maximum = 4.80)
10. PRE10YAVG Definition: For event types R and S, this is the average ringwidth for the 10 years preceeding the growth-change. For event type C, this attribute is left blank. Units: millimeters Domain: range (minimum = 0.1  maximum = 9.8)
11. R_INSAMPLE Definition: Number of R events detected in a sample. The value for this attribute is recorded only once per sample, on the record that contains the event type C for the sample. Otherwise the value is left blank. Units: number Domain: range (minimum = 0.  maximum = 10.)
12. S_INSAMPLE Definition: Number of S events detected in a sample. The value for this attribute is recorded only once per sample, on the record that contains the event type C for the sample. Otherwise the value is left blank. Units: number Domain: range (minimum = 1.  maximum = 14.)
13. LENTOGC Definition: Number of years until occurrence of the next growth-change (Event type = R or S) Units: number Domain: range (minimum = 0.  maximum = 388.)
14. SPECIES Definition: Tree species Domain: enum
15. X Definition: Plot measurement in east-west direction from plot 0 Units: meters Domain: range (minimum = -29.70  maximum = 129.21)
16. Y Definition: Plot measurement in north-south direction from plot 0 Units: meters Domain: range (minimum = -218.09  maximum = 25.69)
17. Z Definition: Plot altitude measurement Units: meters Domain: range (minimum = 683.22  maximum = 745.68)
18. CLASSES Definition: Groupings that were useful for the original study, and that additionally record whether a tree was live or dead just before harvestr in autrumn 1992.. Domain: enum
