UHECRs deflections in the IRAS PSCz catalogue based models of   extragalactic magnetic field
  We present an investigation of the propagation of Ultra High Energy Cosmic Rays (UHECRs) in extragalactic magnetic field (EGMF). We use the IRAS PSCz catalogue in order to reconstruct EGMF taking into account power-law dependence between the magnetic field and the infrared luminosity density. Contrary to the previous works [11] the normalization parameters have been estimated according to the observable values of magnetic field of the galaxy clusters (B_GC = 0.3 - 2 microG) and assessed values of field in the voids of the Local Universe (B_Void = 1 pG - 100 pG). We construct the full-sky maps of expected deflection angles of UHE protons with the arrival energies E = 100 EeV and E = 40 EeV in the reconstructed EGMF for two boundary cases of "strong" (B_GC=2 microG, B_Void = 100 pG) and "weak" (B_GC=0.3 microG, B_Void = 1 pG) magnetic fields. It is found that average deflections of protons with observable energies above 40 EeV and maximum energy in sources E_max = 10 ZeV are unimportant (comparable with the errors of modern detectors) only in the case of "weak" EGMF model.
