-
class
sherpa.astro.xspec.XSnsa(name='nsa')[source]¶ Bases:
sherpa.astro.xspec.XSAdditiveModelThe XSPEC nsa model: neutron star atmosphere.
The model is described at [1].
-
LogT_eff¶ The log of Teff, the unredshifted effective temperature.
-
M_ns¶ The neutron star gravitational mass, in units of the solar mass.
-
R_ns¶ The neutron star radius, in km.
-
MagField¶ The neutron star magnetic field strength, in Gauss. It must be fixed at one of 0, 1e12, or 1e13 G.
-
norm¶ The normalization is 1/D^2, where D is the distance to the neutron star in pc.
