|AHELP for CIAO 4.3 Sherpa v1||
APEC thermal plasma model with velocity broadening as a free parameter. XSpec model.
A version of the xsapec model. Thermal line broadening is automatically included.
This is an additive model component.
|1||kt||plasma temperature in keV|
|2||abundanc||metal abundances (He fixed at cosmic). The elements included are C, N, O, Ne, Mg, Al, Si, S, Ar, Ca, Fe, Ni. Abundances are set by the set_xsabund command.|
|4||velocity||velocity broadening [km/s]|
|5||norm||10^-14 / (4 pi (D_A*(1+z))^2) Int n_e n_H dV, where D_A is the angular size distance to the source (cm), n_e is the electron density (cm^-3), and n_H is the hydrogen density (cm^-3)|
This information is taken from the XSpec User's Guide. Version 12.6.0l of the XSpec models is supplied with CIAO 4.3.
