- "**TARDIS** has the functionality to track the properties of the *RPackets* that are generated when running the Simulation. The `rpacket_tracker` can track all the interactions a packet undergoes & thus keeps a track of the various properties, a packet may have.
Currently, the `rpacket_tracker` tracks the properties of all the rpackets in the *Last Iteration of the Simulation*. It generates a `List` that contains the individual instances of `RPacketCollection`{`Numba JITClass`}, for storing all the interaction properties as listed below."
