the fundamental property of the used magnetic field model in halo. The used model of an azimuthal field is simply focusing all positions into the direction of Galactic north pole and M87 is lying near to this pole, and so the small angular distance between computed EHECR positions and between M87 is probably just an interesting coincidence without fundamental physical importance. Furthermore, such strong magnetic halo is in contradiction with recent observations.

The second work was published by [@harariold] and it proposes the Galactic magnetic wind extending to 1.5 Mpc. The model examines focusing abilities of magnetic wind. Model of the magnetic wind used in this work is purely azimuthal: $$B = B_7 \frac{r_0}{r} \sin \theta \tanh \left( \frac{r}{r_s} \right),$$ It describes $B$ as a function of the radial spherical coordinate $r$ and the angle to the north galactic pole $\theta$. The term $r_0$ in this equation is the distance from the Earth to the Galactic center (equal to 8.5 kpc), factor $r/r_s$ was introduced to smooth out the field at small radii ($r_s$ was taken as 5 kpc). $B_7$ is the normalization factor (the strength of the field in \[7 $\mu$G\] units) and so in conservative models of GMF
