Conditions of use/Licence

BLUE TIT: The dataset is free to explore. We do however ask potential users to contact us if they want to integrate the data to an existing project, publish any derivative analyses based on the data or in any other way use it to produce published or openly available outputs.
GREAT TIT: Upon agreement with the data owner.
Data available via pipeline No
Quality check of the original data

BLUE TIT: At current stage the database is undergoing significant revision and consolidation, including quality checks. However, as always, errors may persist. We do ask all users of this set to communicate all detected errors or inconsistencies to us.
GREAT TIT: check of ring numbers and morphological measurements (eliminating impossible values)
