Table 2.
Comparison of light ring years identified visually on the basis of dark colour of latewood visible on X-ray films with light ring years distinguished on the basis of low maximum density values. Asterisks indicate the values lower than accepted threshold of light ring years. Calendar years used during calculation of relationship between light rings and climate parameters are marked in bold.
