gris targets: redundant vocabulary
The targets specified in the headers and or db are not consistent. e.g. Emerging flux Region and Emerging Flux Reg. need to be consolidated.
Full consolidation includes:
- Check where the tag names originate
- Decide on a consistent naming convention
- Open issues regarding enforcing and documenting said scheme
- Fix the names in all datasets, starting at L0 headers
- Fix the names in the corresponding observation entries
