APC and open-access policy
Hybrid open accessLetPub
A subscription journal in which authors can pay to publish their article open access.

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.
