keyword=SOS sieve slitsThe SOS sieve slit reconstruction is dependent on the central momentum. Figs 1 and 2 show the reconstruction at high and low central momenta.
Apart from the fact that higher momenta data suffer from much less background, it can be seen that the reconstruction is good at high momenta (where the matrix elements have been fitted), while at low excitation there are aberrations. While in general xptar is not affected, there is an xptar dependent aberration in the reconstruction of the yptar holes. Since these plots integrate over all delta and yptar, the effect washes out a bit. But at high xptar it can clearly be seen that events are projected to |yptar| values lower than they should be.
