Emission reactions take the form:

\[ \rightarrow \mbox{X} \]

where \(\ce{X}\) is the species being emitted.

Emission rates can be constant or set from an external module using the camp_rxn_emission::rxn_update_data_emission_t object. External modules can use the camp_rxn_emission::rxn_emission_t::get_property_set() function during initilialization to access any needed reaction parameters to identify certain emission reactions. An camp_rxn_emission::update_data_emission_t object should be initialized for each emissions reaction. These objects can then be used during solving to update the emission rate from an external module.

Input data for emission reactions have the following format :

{
  "type" : "EMISSION",
  "species" : "species_name",
  "scaling factor" : 1.2,
  ...
}

The key-value pair species is required and its value must be the name of the species being emitted. The scaling factor is optional, and can be used to set a constant scaling factor for the rate. When a scaling factor is not provided, it is assumed to be 1.0. All other data is optional and will be available to external modules during initialization. Rates are in units of \(\mbox{concentration units} \quad s^{-1}\), and must be set using a rxn_update_data_emission_t object.
