I actually have a surprising amount of experience in Fortran, as both of my major "research" projects in college had to do with legacy Fortran code bases. The first was fitting a series of potential energy calculation libraries with Mathematica bindings, and the second was converting a library that did a particular kind of blur and glob detection to FITS datasets to C. The second one was extra fun because the library was actually written in "FORCE", an extensive macro-extension of Fortran, for which we no longer had a compiler. All I had was docs, the original published paper, the original source, and a handful of input-output examples on substantial datasets (for context, the datasets were essentially a 1024 x 1024 x 1024 array of floats that needed to be convolved with two different Gaussian kernels and compared pixel by pixel in an interesting way).
