METHODOLOGICAL INFORMATION
-------------------------
1. Description of methods used for collection/generation of data:
AAll surveys were conducted using scuba equipment between 8-10 meters depth. At each site, four 30-m transects were deployed at least five meters apart, and 15 pictures were taken every other meter at each transect. As reference, two types of frames were included in the picture for scaling: a yellow-black bar indicating 10cm for each colored segment; and an L-shaped bar with perforations, the separation between two perforations also being 10cm.
2. Instrument- or software-specific information needed to interpret the data:
Images can be opened with any visualizer. Annotation can be performed with software like [CPCe](https://cnso.nova.edu/cpce/index.html), [Photoquad](https://www.mar.aegean.gr/sonarlab/photoquad/index.php), [CoralNet](https://coralnet.ucsd.edu/source/about/), or similars
3. People involved with sample collection, processing, analysis and/or submission:
All authors were involved at the field surveys and/or data processing.
