Context: models

Synopsis

The XSPEC kdblur2 convolution model: convolve with the laor2 model

Syntax

xskdblur2

The xskdblur2 model is a convolution model component.

Description

The model is described at [1] .

Example

>>> create_model_component("xskdblur2", "mdl")
>>> print(mdl)

Create a component of the xskdblur2 model and display its default parameters. The output is:

mdl
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
   mdl.Index    frozen            3          -10           10

   mdl.Rbreak   frozen           20        1.235          400           
   mdl.Index1   frozen            3          -10           10

ATTRIBUTES

The attributes for this object are:

Attribute	Definition
Index	The power law dependence of emissivity (scales as R^-Index).
Rin_G	The inner radius, in units of GM/c^2.
Rout_G	The outer radius, in units of GM/c^2.
Incl	The disk inclination angle, in degrees. A face-on disk has Incl=0.
Rbreak	The radius at which the emissivity power-law index changes.
Index1	The emissivity power-law index for r>Rbreak.

Notes

Unlike XSPEC, the convolution model is applied directly to the model, or models, rather than using the multiplication symbol.
