1. A method for generating a data sequence at an elevation angle ϑ and an azimuth angle φ, the method comprising:
obtaining a first set of azimuth basis function values for the azimuth angle, wherein obtaining the first set of azimuth basis function values comprises: for each azimuth basis function included in a first set of azimuth basis functions, evaluating the azimuth basis function at the azimuth angle to produce an azimuth basis function value corresponding to the azimuth angle and the azimuth basis function, and further wherein each of the azimuth basis functions included in the first set of azimuth basis functions is a periodic basis function; and
using the first set of azimuth basis function values to generate the data sequence at the elevation angle and azimuth angle.
