Fortran95 Software for spherical harmonic transforms

• module for gaussian grids, triangular truncation  spharmt.f90 (module source) test_spharmt.f90 (test program)
• Fortran95 interface to spherepack. Works with both gaussian and regularly spaced grids, triangular truncation only.   sphere.f90 (module source) test_sphere.f (test program) Makefile (sample Makefile) README.  See module source for documentation.  For gaussian grids the spharm module is much faster. A python binding for spherepack is also available here
