xsrdblur

Context: models

Synopsis

The XSPEC rdblur convolution model: convolve with the diskline model shape

Syntax

xsrdblur

The xsrdblur model is a convolution model component.

Description

The model is described at [1] .


Example

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

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

mdl
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
   mdl.Betor10  frozen           -2          -10           20           
   mdl.Rin_M    frozen           10            6        10000           
   mdl.Rout_M   frozen         1000            0        1e+07           
   mdl.Incl     thawed           30            0           90        deg

ATTRIBUTES

The attributes for this object are:

Attribute Definition
Betor10 The power law dependence of emissivity: see [1] for more details.
Rin_M The inner radius, in units of GM^2/c.
Rout_M The outer radius, in units of GM^2/c.
Incl The inclination, in degrees.

Notes

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

Changes in CIAO

Added in CIAO 4.13

XSPEC version

CIAO 4.16 comes with support for version 12.13.1e of the XSPEC models. This can be checked with the following:

% python -c 'from sherpa.astro import xspec;
print(xspec.get_xsversion())'
12.13.1e
