Date symbol:
    B = bark is present.
    p = pith ring is present.
    ± p = pith ring is present, but due to the difficult nature of the ring series near the center of the specimen, an exact date cannot be assigned to it. The date is obtained by counting back from the earliest dated ring.
    r = less than a full section is present, but the outermost ring is continuous around available circumference.
    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.
