Description
In this work, we consider the case of a model GWB source with a Gaussian power spectrum on a sphere, and obtain an analytical expression of the overlap reduction function of the signals of two pulsars, which generalizes the previously obtained expressions for isotropic and delta-shaped model sources. Using the generalized correlation function allows us to determine the characteristic angular size of the source. Such signals can arise in some models of new physics, e.g. oscillating loops from a single cosmic string. The algorithm was tested on simulated datasets of pulsars with isotropic and anisotropic sky distribution.
