J0 and J1-transforms

This is a library of routines that computes integrals of the form \int_0^\infty dx J0(kx)F(x) or \int_0^\infty dx J1(kx) F(x). It is an improvement (faster, and more accurate at the same time) over code contained in the package that calculates the dipole cross-section. It makes use of the Gnu Scientific Library.
The compressed tar archive containing the library is available at fourier.tar.gz. Although the core of the library is written in C, there is a wrapper library in order to make its routines callable from a program written in FORTRAN. Example programs using this library are provided both for C and FORTRAN.
