A version of the XSPEC model raymond, with independent variables for all abundances and for the continuum. This model interpolates on a grid of spectra for different temperatures. The grid is logarithmically spaced with 80 temperatures ranging from 0.008 to 80 keV. Abundances are the number of nuclei per Hydrogen nucleus relative to the Solar abundances as set by the abund command.
par1 = plasma temperature (keV)par2-par13 = Abundances for He, C, N, O, Ne, Mg, Si, S,
Ar, Ca, Fe, Ni wrt Solar (defined by the abund command)
par14 = redshift z
K =
, where D is the distance to the
source (cm),
and
are the electron and H densities (cm
)
