This framework creates toy-model simulations of 200 GeV Au+Au heavy ion collisions and calcualtes jet $v_{n}$ through mixed cumulants.

The toy-model created in simulation takes a stand alone version of TennGen to create 200 GeV Au+Au backgrounds with a set event plane and particle $v_{N}$. The background can be made for 0-10%, 10-20%, 20-40% and 40-60% central collisions with a maximum psuedo-rapidity of $|\eta| < 1.1$. The background only consists of $\pi^{\pm}$, $k^{\pm}$, $p$, and $\bar{p}$. The signal jets are simualted with PYTHIA 8 200 GeV $p$+$p$ collisions. All final state particles are saved from the PYTHIA event. The FastJet3 is used to find anti-$k_{T}$ jets for $R = 0.4$ jets. The leading jet is then aligned to match a $\frac{dN_{jet}}{d\phi}$ distribution where the event-plane is defined by the TennGen event plane and the jet $v_{n}$ is set by the user. The entire Pythia event is then rotated and merged with the TennGen background.

The analyis macro takes in the mixed, re-aligned event and finds anti-$k_{T}$ jets with $R=0.4$ and a $p_{T}^{min} = 10$ GeV.
