PD: Provenience designation number

FS: Field specimen number

PL: Point location number

Inside Date: Inside date

Inside Date Suffix: Inside date suffix

year - no pith ring present
p - pith ring present
fp - the curvature of the inside ring indicates that it is far from the pith
+/-p - pith ring present, but exact date cannot be assigned due to difficult rings near center; date is obtained by counting back from earliest dated ring
+/- - the innermost ring is not the pith ring and an absolute date cannot be assigned to it; a ring count is involved

Outside Date: Outside date

Outside Date Suffix: Outside date suffix

b - bark present.
g - beetle galleries are present on the surface of the specimen.
l - a characteristic surface patination and smoothness, which develops on beams stripped of bark, is present.
c - the outermost ring is continuous around the full circumference of the specimen; symbol is used only if a full section is present.
r - less than a full section is present, but the outermost ring is continuous around available circumference.
v - subjective judgement that, although there is no direct evidence of the true outside on the specimen, the date is within a very few years of being a cutting date
vv - there is no way of estimating how far the last ring is from the true outside.
+ - one or more rings may be missing near the end of the ring series whose presence or absence cannot be determined because the specimen does not extend far enough back to provide an adequate check.
++ - a ring count is necessary due to the fact that beyond a certain point the specimen could not be dated.
