Two of five datasets state terms on the pages read: DIV2K says it is made available for academic research purpose only (copyright with the original owners), and REDS says CC BY 4.0. The Vimeo-90K project page and repository README, the Flickr2K section of the EDSR/NTIRE2017 README, and the OST project page and README state origin and download links but no terms. Absence is bounded to those pages: the Vimeo-90K dataset subpage returned 403, and no separate terms page was found for Flickr2K or OST.

Curator qualifications: Excerpted evidence located (one unexcerpted row); dataset pages' licence/terms statements (often absent).

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
