| Research Abstract |
To estimate the calendar age of the outermost ring of the historical wooden material by wiggle matching, 14C age should be measured for most of its annual rings. The matching error is, however, greatly dependent on the calendar-age range to be fitted. The error is large for the calendar-age period where 14C age does not change much and is rather constant. When 14C age shows an inverse-N-shaped change in increase of calendar age, the wiggle matching analysis may show two possible age ranges. The error of wiggle matching even for only two annual ring samples is rather small for the period where 14C age changes monotonously and rapidly.
