[Hps-analysis] invariant mass Data VS My MC

[Maurik Holtrop]

Hi Luca,

I am really glad that at least you are up and running again with code. Probably should not update your trunk, or at least preserve your current one, so it doesn’t get messed up.

Did you impose any additional cuts to your data sample?  It looks like you did not and so have a large amount of extra background.
Also, does the MC sample include full beam background, or is this only the tridents?

Cheers,
	Maurik
