Date symbol:
    p = pith ring is present.
    ± = the innermost ring is not the pith ring, and an absolute date cannot be assigned to it. A ring count is involved.
    r = less than a full section is present, but the outermost ring is continuous around available circumference.
    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.
