Community reports come from authors' own submissions (confidence 0.5) and are not a promise from the journal; for publisher figures, the journal's own definitions apply.

A hybrid journal charges the APC only when the author chooses open access; publishing under the subscription model is usually free.

The journal's website is authoritative for fees; sources were observed at different times and each keeps its own value, without averaging.
