Pair plasma model.
XSpec model.
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). The abundances are set up by the xspecabundan command.
xsnteea Parameters
| 1 | lnth | nonthermal
electron compactness |
| 2 | lbb | blackbody
compactness |
| 3 | frefl | scaling factor
for reflection; 1 = isotropic source above disk |
| 4 | kTbb | blackbody
temperature in eV |
| 5 | gmax | the maximum
Lorentz factor |
| 6 | lth | thermal
compactness; 0 = pure nonthermal plasma |
| 7 | taup | Thomson optical
depth of ionization electrons (e.g. 0) |
| 8 | Ginj | electron
injection index; 0 = monoenergetic injection |
| 9 | gmin | minimum Lorentz
factor of the power law injection; not used for monoenergetic
injection |
| 10 | g0 | minimum Lorentz
factor for nonthermal reprocessing; 1 < g0 <= gmin |
| 11 | radius | radius in cm
(for Coulomb/bremsstrahlung only) |
| 12 | pairesc | pair escape
rate in c; 0 <= paires <= 1, see Zdziarski 1985, ApJ, 289, 514 |
| 13 | cosIncl | cosine of
inclination angle |
| 14 | FeAbund | iron
abundance relative to that defined by xspecabundan |
| 15 | Redshift | redshift,
z |
| 16 | norm | photon flux of
the direct component without reflection at 1 keV in the observer's
frame. |
