The emission due to electron-electron bremsstrahlug from a collisionally-ionized gas. Uses the approximations from Nozawa et al (2009). This component is already included in all the apec-derived models if APECEEBREMSS is xset to yes.

par2 | The number of electrons per H nucleus. The default is 1.2. |
par3 | Redshift, z |
norm | , where is the angular diameter distance to the source (cm), is the volume element (cm), and and are the electron and H densities (cm), respectively |
