Data levels that used in the different descriptions of available data are:
- Level 0 data : Reduced calibrations
- Level 1 data: science master cubes, associated to complementary files such as adaptive optics information
- Level 2 data: final images (stacked using various algorithms), possibly associated to complementary files such as frame sorting information, SNR maps, contrast curves …
- Level 3 data: Detections of sources in final images (for exoplanet studies, but they are not necessarily companions) associated to informations on the targets.
