In the methods section of the paper I list the major software packages I used for the research, including any references to academic papers written about that software (e.g. many authors of scientific software are publishing with journals like the *Journal of Open Research Software* so they can get academic credit for their work). Since Iris uses proj.4 for grid rotation, I'd like to reference proj.4 if possible. Is there an appropriate reference that I could cite?  "}}
