By means of $ab \ initio$ band structure methods and model Hamiltonians weinvestigate the electronic, spin and topological properties of fourmonopnictides crystallizing in body centered tetragonal structure. We show thatthe Weyl bands around a Weyl point W1 or W2 possess a strong anisotropy andtilt of the accompanying Dirac cones. These effects are larger for W2 nodesthan for W1 ones. The node tilts and positions in energy space significantlyinfluence the density of states of single-particle Weyl excitations. The nodeanisotropies destroy the conventional picture of (anti)parallel spin and wavevector of a Weyl fermion. This also holds for the Berry curvature around anode, while the monopole charges are independent as integrated quantities. Thepairing of the nodes strongly modify the spin texture and the Berry curvaturefor wave vectors in between the two nodes. Spin components may change theirorientation. Integrals over planes perpendicular to the connection line yieldfinite Zak phases and winding numbers for planes between the two nodes, therebyindicating the topological character.
