The 6 bins in centrality have different values of $E^0/E^0_{beam}$ at 40 and 158$A$ GeV since the acceptance of the forward calorimeter depends on beam energy.
000607692 8564_ $$82516106$$s73123$$uhttps://cds.cern.ch/record/607692/files/systBxBy.png$$y00006 (Color online) Rapidity dependence of pion elliptic flow for different cuts on the track impact parameter. The sets of the cuts were chosen to be 1.0 cm for $b_x$ and 0.2 cm for $b_y$ for the tight cut. For the open case no cut was used. The standard cut is 3.0 cm for $b_x$ and 0.5 cm for $b_y$.

The open points have been reflected about midrapidity. Solid lines are polynomial fits. Please note the different vertical scales.
000607692 8564_ $$82516108$$s24439$$uhttps://cds.cern.ch/record/607692/files/40_v_cen.png$$y00023 (Color online) Directed and elliptic flow as a function of centrality for charged pions (top) and protons (bottom) from 158$A$ GeV Pb + Pb (left) and 40$A$ GeV Pb + Pb (right) from the standard analysis. Shown are $v_1$ (circles) and $v_2$ (squares). The more central collisions are on the left side of each graph. Solid lines are polynomial fits.

000607692 8564_ $$82516112$$s22908$$uhttps://cds.cern.ch/record/607692/files/v2_over_eps.png$$y00029 (Color online) $v_2/\epsilon$ as a function of particle density. The $v_2$ values are for near mid-rapidity ($0 < y < 0.6$ for 40$A$ GeV and $0 < y < 0.8$ for 158$A$ GeV). The results of NA49 pion $v_2$ are compared to charged particle $v_2$ measured by E877 and STAR. The meaning of the horizontal lines (hydro limits) and of the arrow will be discussed in Sec.~\ref{s:models}.
000607692 8564_ $$82516113$$s23808$$uhttps://cds.cern.ch/record/607692/files/v1_scaled_eComp.png$$y00026 (Color online) A comparison of directed and elliptic flow of charged pions at 40 and 158$A$ GeV using the standard method is shown as a function of scaled rapidity. The left graph for $v_1$ is for peripheral collisions and the right graph for $v_2$ is for mid-central collisions. The open points have been reflected about midrapidity.
