**sphere_exactness_test**,
a C++ code which
calls sphere_exactness(), which
investigates the polynomial exactness of a quadrature rule
over the surface of the unit sphere in 3D.

sphere_exactness, a C++ code which tests the monomial exactness of a quadrature rule over the surface of the unit sphere in 3D.

- sphere_exactness_test.sh, runs all the tests.
- sphere_exactness_test.txt, the output file

- design_04.xyz contains the XYZ coordinates of a spherical design of precision 4. Uniform weights are used.
- lebedev_013.dtpw contains a the 74 Lebedev rule of precision 13. Weights are specified, and the data is stored in the "DTPW" format, that is, theta and phi are specified in degrees.
