摘要: We present numerical simulations for the two-point correlation function and angular power spectrum of nucleons above ${10}^{19}\mathrm{eV}$ injected by a discrete distribution continuously emitting sources which follow simple approximation to profile Local Supercluster. develop method constrain number necessary reproduce observed sky ultrahigh energy cosmic rays, as strength large scale magnetic fields in While $B\ensuremath{\lesssim}0.05\ensuremath{\mu}\mathrm{G}$ Supercluster source appears inconsistent with data any sources, $B\ensuremath{\simeq}0.3\ensuremath{\mu}\mathrm{G}$ could around 10.
