Description
The scan table provides scans all information available of sanning process of the photographic plates, giving sizes, etc. A scan is a high-resolution image of a photographic plate or film. In the case of the Solar plates, we provide the already preprocessed images, details see level 1 description. Unique Identifier scan_id.
