Thanks again for your link. I am already aware of how to do multiple integrals.

I am looking for an efficient quadrature rules for spherical caps. I am aware of quad rules over tetrahedral, cube, sphere, etc. I was wondering if there are some standard techniques for spherical caps too.
On searching for published papers on google scholar I get links to papers which are too mathematical for me to interpret.

Any pointers on that will be really helpful- or I would welcome any other suggestions which will give me some elegant solution to the problem. Thanks.
