XScyclabs

class sherpa.astro.xspec.XScyclabs(name='cyclabs')[source] [edit on github]

Bases: sherpa.astro.xspec.XSMultiplicativeModel

The XSPEC cyclabs model: absorption line, cyclotron.

The model is described at [1].

Depth0

The depth of the fundamental.

E0

The cyclotron energy, in keV.

Width0

The width of the fundamental, in keV.

Depth2

The depth of the second harmonic.

Width2

The width of the second harmonic, in keV.

get_center() [edit on github]
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) [edit on github]
reset() [edit on github]
set_center(*args, **kwargs) [edit on github]
startup() [edit on github]

Called before a model may be evaluated multiple times.
