From https://joss.theoj.org/about#costs :

> Income: JOSS has an experimental collaboration with AAS publishing where authors submitting to one of the AAS journals can also publish a companion software paper in JOSS, thereby receiving a review of their software. For this service, JOSS receives a small donation from AAS publishing. In 2019, JOSS received $200 as a result of this collaboration.
