Date symbol:
B = bark is present.
p = pith ring is present.
v = a subjective judgment that, although there is no direct evidence of the true outside on the sample, 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. Many rings may be lost.
+ = one or a few rings may be missing near the outside whose presence or absence cannot be determined because the series does not extend
far enough to provide adequate crossdating.
++ = a ring count is necessary beyond a certain point in the series because crossdating ceases.
