BBodyFreq

class sherpa.astro.models.BBodyFreq(name='bbodyfreq')

Bases: sherpa.models.model.ArithmeticModel

A one-dimensional Blackbody model (frequency).

This model can be used when the independent axis is in frequency space.

T

The temperature if the blackbody, in Kelvin.

ampl

The amplitude of the blackbody component.

Notes

The blackbody emission is calculated as a function of frequency (v) using Wien’s law (hv >> kT):

f(v) = ampl * 2 * h * v^3 * exp(-h * v / (k * T)) / c^2

where T is the blackbody temperature in Kelvin, h is Planck’s constant, k is Boltzmann’s constant, and c the speed of light.
