bremsstrahlung

Context: models

Synopsis

Bremsstrahlung emission.

Syntax

bremsstrahlung

Description

It is for use when the independent axis is in Angstroms.

Example

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

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

mdl
   Param        Type          Value          Min          Max      Units
   -----        ----          -----          ---          ---      -----
   mdl.refer    frozen         5000  1.17549e-38  3.40282e+38  angstroms
   mdl.ampl     thawed            1  1.17549e-38  3.40282e+38  angstroms
   mdl.temperature thawed         3000  1.17549e-38  3.40282e+38     Kelvin

ATTRIBUTES

The attributes for this object are:

Attribute	Definition
refer	The reference point, in Angstroms.
ampl	The amplitude of the emission. Note that the model does not equal ampl at the reference point, as shown in the functional form below.
temperature	The temperature in Kelvin.

Notes

The functional form of the model for points is:

f(x) = ampl * (refer/x)^2 * exp(-1.438779E8 / temperature / x)

and for integrated data sets the low-edge of the grid is used.
