Synopsis
Pair plasma model. XSpec model.
Description
A nonthermal pair plasma model based on that of Lightman and Zdziarski (1987, ApJ 319, 643) from Magdziarz and Zdziarski. It includes angle-dependent reflection from Magdziarz and Zdziarski (1995, MNRAS 273, 837). In versions 1.1 and above the Compton reflection is done through an internal call to the reflct model. The Greens' function integration required for the Compton reflection calculation is performed to an accuracy of 0.01 (i.e. 1%). This can be changed using, e.g., 'xset NTEEA_PRECISION 0.05' (see 'ahelp set_xsxset'). The abundances are set up by the set_xsabund command (see 'ahelp set_xsabund').
This is an additive model component.
xsnteea Parameters
| Number | Name | Description |
|---|---|---|
| 1 | l_nth | nonthermal electron compactness |
| 2 | l_bb | blackbody compactness |
| 3 | f_refl | scaling factor for reflection; 1 = isotropic source above disk |
| 4 | kt_bb | blackbody temperature in eV |
| 5 | g_max | the maximum Lorentz factor |
| 6 | l_th | thermal compactness; 0 = pure nonthermal plasma |
| 7 | tau_p | Thomson optical depth of ionization electrons (e.g. 0) |
| 8 | g_inj | electron injection index; 0 = monoenergetic injection |
| 9 | g_min | minimum Lorentz factor of the power law injection; not used for monoenergetic injection |
| 10 | g_0 | minimum Lorentz factor for nonthermal reprocessing; 1 < g0 <= gmin |
| 11 | radius | radius in cm (for Coulomb/bremsstrahlung only) |
| 12 | pair_esc | pair escape rate in c; 0 <= paires <= 1, see Zdziarski 1985, ApJ, 289, 514 |
| 13 | cosincl | cosine of inclination angle |
| 14 | fe_abund | iron abundance relative to that defined by set_xsabund |
| 15 | redshift | redshift, z |
| 16 | norm | photon flux of the direct component without reflection at 1 keV in the observer's frame. |
