Emission from a black body as a function of wavelength.
It is for use when the independent axis is in Angstroms.
>>> create_model_component("blackbody", "mdl") >>> print(mdl)
Create a component of the blackbody 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
The attributes for this object are:
The reference point, in Angstroms.
The amplitude of the emission; it is defined at the reference point but its numerical value there also depends on the temperature.
The temperature in Kelvin.
The functional form of the model for points is:
f(x) = ampl * g(refer) / g(x) g(x) = x^5 * (exp(1.438786E8 / temperature / x) - 1)
and for integrated data sets the low-edge of the grid is used.
