accretion disk line shape with BH spin as free parameter. XSpec convolution model *Experimental*.
Convolves the current spectrum with the line shape from the kerrdisk model. A detailed description can be found in Brenneman & Reynolds (2006ApJ...652.1028B). This model is quite slow so is best used after models such as laor or diskline have been employed to get an estimate of the best-fit parameters.
|1||Index1||emissivity index for the inner disk|
|2||Index2||emissivity index for the outer disk|
|3||r_br_g||break radius separating the inner and outer portions of the disk (gravitational radii)|
|4||a||dimensionless black hole spin|
|5||Incl||disk inclination angle to the line of sight (degrees)|
|6||Rin_ms||inner radius of the disk in units of the radius of marginal stability|
|7||Rout_ms||outer radius of the disk in units of the radius of marginal stability|
Loading the X-Spec convolution models
Please see ahelp xsconvolve for information on how to load the model.
- This is an experimental release of the convolution models; please take care when using this model.
This information is taken from the XSpec User's Guide. Version 12.10.0e of the XSpec models is supplied with CIAO 4.11.
sherpa> from sherpa_contrib.xspec.xsconvolve import load_xskerrconv sherpa> load_xskerrconv("kdb") sherpa> set_source(kdb(xspowerlaw.pl + xsgaussian.gs)) sherpa> kdb.incl = 45
The powerlaw and gaussian components are convolved by the kerrconv model, whose inclination angle is set at 45 degrees.
