COFECHA is a quality-control program used to check the crossdating and overall
quality of tree-ring chronologies. A modified form of COFECHA has been run on
the chronologies in the ITRDB, during two quality-control projects
completed in 1996 and 2005, respectively. The COFECHA output file for each chronology provides
important information about chronology quality. The online user guide will aid
in the interpretation of that information.
