.- Parameters
in_x : number, array_like, or
Quantity
Frequency, wavelength, or wave number. If not a Quantity, it is assumed to be in Hz.
- temperaturenumber, array_like, or
Quantity
Blackbody temperature. If not a Quantity, it is assumed to be in Kelvin.
- temperaturenumber, array_like, or
- Returns
flux :
Quantity
Blackbody monochromatic flux in \(erg \; cm^{-2} s^{-1} Hz^{-1} sr^{-1}\).
- Raises
ValueError
Invalid temperature.
- ZeroDivisionError
Wavelength is zero (when converting to frequency).
