Comptonized blackbody model by Nishimura, Mitsuda and Itoh (1986, PASJ 38, 819). The electron temperature should normally be kept fixed since the Compton parameter is the product of the electron temperature and optical depth.
par1 | blackbody temperature (keV) |
par2 | electron temperature of the hot plasma (keV) |
par3 | optical depth of the plasma |
norm | , where is the source luminosity in units of erg/s and is the distance to the source in units of 10 kpc (the same definition used for the bbodyrad model) |
