XSswind1¶

class sherpa.astro.xspec.XSswind1(name='swind1')[source]¶

Bases: sherpa.astro.xspec.XSMultiplicativeModel

The XSPEC swind1 model: absorption by partially ionized material with large velocity shear.

The model is described at [1].

Note

Deprecated in Sherpa 4.10.0

The logxi parameter has been renamed log_xi to match the XSPEC definition. The name logxi can still be used to access the parameter, but this name will be removed in a future release.

column¶: The column density, in units of 10^22 cm^2.

log_xi¶: The log of xi: see [1] for more details.

sigma¶: The gaussian sigma for velocity smearing (v/c).

redshift¶: The redshift of the source.

apply(outer, *otherargs, **otherkwargs)¶

calc(pars, xlo, *args, **kwargs)¶

get_center()¶

guess(dep, *args, **kwargs)¶

Set an initial guess for the parameter values.

Attempt to set the parameter values, and ranges, for the model to match the data values. This is intended as a rough guess, so it is expected that the model is only evaluated a small number of times, if at all.

reset()¶

set_center(*args, **kwargs)¶

startup()¶

teardown()¶
