How to Run TARDIS with a Custom Packet SourceΒΆ

By default, TARDIS generates energy packets using its interface BasePacketSource class, which has a derived class BlackBodySimpleSource, which models the photosphere of the supernova as a perfect blackbody (see Energy Packet Initialization). However, users may create their own packet source, as will be shown in this notebook. In order to do this, a user must create a class (that inherits from BasePacketSource) and implement the following abstract functions:

  • create_packet_radii (returns array of packet radii)

  • create_packet_nus (returns array of packet frequencies)

  • create_packet_mus (returns array of packet directions)

  • create_packet_energies (returns array of packet energies. See Energy Packet Initialization for more information)

  • create_packets (wrapper which calls the above 4 functions, and is the function used by external code)

  • set_state_from_model (set the state of the source from a model object)

[Note: In this notebook, we have extended the BlackBodySimpleSource class because it already implements some of the above functions]

To use your packet source in a run of TARDIS, you must pass an instance of your class into the run_tardis function under the packet_source keyword argument.

Note

In both the BlackBodySimpleSource class and in the example here, all packets are generated at the same radius. This need not be true in general (though one call of the create_packets method will pick the same radius from the packet source state).

We show an example of how a custom packet source is used:
