XSzxipcf
(name='zxipcf')[source] [edit on github]¶ Bases:
sherpa.astro.xspec.XSMultiplicativeModel
The XSPEC zxipcf model: partial covering absorption by partially ionized material.
The model is described at [1].
Note
Deprecated in Sherpa 4.10.0
The
logxi
parameter has been renamedlog_xi
to match the XSPEC definition. The namelogxi
can still be used to access the parameter, but this name will be removed in a future release.-
nH
¶ The column density, in units of 10^22 cm^2.
-
CvrFract
¶ The covering fraction.
-
redshift
¶ The redshift of the source.

guess
(dep, *args, **kwargs) [edit on github]¶ 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.
-
regrid
(*arrays, **kwargs) [edit on github]¶ The class RegriddableModel1D allows the user to evaluate in the requested space then interpolate onto the data space. An optional argument ‘interp’ enables the user to change the interpolation method.
Examples
>>> import numpy as np >>> from sherpa.models.basic import Box1D >>> mybox = Box1D() >>> request_space = np.arange(1, 10, 0.1) >>> regrid_model = mybox.regrid(request_space, interp=linear_interp)
