Example for missing ring:

In core C045094 (black line), a missing tree ring is inserted in 1870 (top), 1871 (middle), and 1872 (bottom). A second core (C044096, in blue) is shown as well as a master chronology (red).

Overlapping rings:

In core C047094 (black line), 1831 and 1832 are false/overlapping rings. Top: The entire black curve has been shifted backward by 2 years (gray curve); bottom: the right (outer) part of C047094 has been shifted from 1833 to 1831 (gray curve).
