Plots for meeting

Yet again I've left it a bit late to describe these here, I'll talk about them in the meeting and then write something here later.

Mass plot for ycut jet finding
We had a go at selecting the hadronic stuff by using ycut jet finding with a low ycut and requiring the jets to have at least 2 tracks. This is the mass plot for the best peak I get.


Comparison
This is that plot overlaid on the perfect particle assignment from Monte Carlo, and the plot from removing photons close to the electrons. The ycut method has a slightly smaller peak than the brem removal method, but smaller high tail which is the important thing.
