pyarts3.arts.physics.planck
- physics.planck(frequency: object, temperature: object) object
- physics.planck(frequency: object, temperature: object) object
Calculates the Planck function.
\[I =\frac{2h\nu^3}{c^2} \frac{1}{e^{\frac{h\nu}{kT}} - 1},\]where \(\nu\) is the frequency and \(T\) is the temperature.
- Parameters:
frequency (Numeric or numpy.ndarray) – Frequency [Hz]
temperature (Numeric or numpy.ndarray) – Temperature [K]
- Returns:
B – Planck function [W/(m² Hz sr)]
- Return type:
