  We investigate consequences of local energy-momentum conservation for initial
eccentricity coefficients in heavy ion collisions at not too high energies
relevant for CERN SPS and RHIC BES. Different models of energy density
available for pion production are considered. We study dependence of
eccentricity coefficients on space-time rapidity for different impact
parameters. The naive formula how to define eccentricities breaks with our
initial conditions and must be corrected. We predict considerable
eccentricities for $\epsilon_{1,2,3,4}$ and specific dependence on space-time
rapidity as well as on impact parameter for lower energies. The effect becomes
smaller at larger energies when restricting to narrow rapidity interval arround
zero. Our predictions are in principle input for further hydrodynamical
evolution but it is not clear whether they can be easily used. Our initial
condition suggest a strong preequilibrium phase which is difficult for
modelling.
