Cooling function

The cooling function is computed as emissivity (erg/molecule/sterradian or Watt/Str/Molecule) on a grid of temperatures (K). Here is an example of the input:

cooling
 Tmax     5000.0
 N  5000
end

output      ScH_adj_16665

Transitions   ScH_adj_16665.trans
States        ScH_adj_16665.states

The colling functionality can be combined with the temperature-list functionality similar to the computation of the parition funciton with partfunc.

 cooling
  list
 end

temperature-list
200
300
1000
end

The default units are erg/molecule/sterradian as the units of emissiom, which can be changed to Watt/Str/Molecule as follows:

cooling
 Tmax     5000.0
 N  5000
 unit Watts
end

Keywords:

  • N or Ntemps is the number of temperature steps

  • Tmax, tempmax, Maxtemp or Max-Temperature is the maximal temperature in K (minimal T = 0K )

  • list: switch use the temperature-list construct.

  • units: swtich to different unins Watts: Watt/Str/Molecule.
