New page

The following is an update on amplitude fits with error bars now including the MC contribution. The effect of detector resolution on the uniform background wave is also shown.

== Background wave and resolution ===

The following are plots of the invariant mass distribution of the resonance from disparate MC sets but they show well how detector resolution effects the strength of the uniform background wave. As a reminder, the generated data included 1<sup>--</sup> and 2<sup>+-</sup> which are fitted here with blue and green points respectively.
