XSnteea

class sherpa.astro.xspec.XSnteea(name='nteea')

Bases: sherpa.astro.xspec.XSAdditiveModel

The XSPEC nteea model: non-thermal pair plasma.

The model is described at [1].

l_nth

The nonthermal electron compactness.

l_bb

The blackbody compactness.

f_refl

The scaling factor for reflection. This is 1 for an isotropic source above the disk.

kT_bb

The blackbody temperature in eV.

g_max

The maximum Lorentz factor.

l_th

The thermal compactness. Set to 0 for a pure nonthermal plasma.

tau_p

The Thomson optical depth of ionization electrons.

G_inj

The electron injection index (0 for monoenergetic injection).

g_min

The minimum Lorentz factor of the power law injection (not used for monoenergetic injection).

g_0

The minimum Lorentz factor for nonthermal reprocessing, in the range (1, g_min].

radius

The radius in cm (for Coulomb/bremsstrahlung only).

pair_esc

The pair escape rate in c.

cosIncl

The cosine of the inclination angle.

Fe_abund

The iron abundance relative to that set by the set_xsabund function.

redshift

The redshift of the source.

norm

The normalization of the model: see [1] for more details.

Notes

The precision of the numerical integration can be changed by using the set_xsxset function to set the value of the NTEEA_PRECISION keyword, which defines the fractional precision. The default is 0.01 (1%).
