Hi all, thanks for these answers. I need to digest all this. Of course, the primary origin (not going back to the original author) would be duly acknowledged. In fact, I've started translating the FORTRAN source. It's so much work that I'm considering writing the Java program from scratch, using the supporting (published papers) only (and maybe copy/pasting the numerical constants -- which are published anyway). Even so, it would probably do no harm to acknowledge this great library (for those who like FORTRAN).
