In this case there are functions as well as data, though... Unless I looped to compute solar position vs time-of-day, date, lat, and long, and interpolated (yuch). We have some separate Fortran/C routines for computing solar position, so I'll probably end up either making command-line utils from them (and calling from Mathematica), or recoding them in Mathematica itself.
