blackbody_nu¶

astropy.modeling.blackbody.blackbody_nu(in_x, temperature)[source]¶

Calculate blackbody flux per steradian, \(B_{\nu}(T)\).

Note

Use numpy.errstate to suppress Numpy warnings, if desired.

Warning

Output values might contain nan and inf.

Parameters:	in_x : number, array-like, or `Quantity` Frequency, wavelength, or wave number. If not a Quantity, it is assumed to be in Hz. temperature : number, array-like, or `Quantity` Blackbody temperature. If not a Quantity, it is assumed to be in Kelvin.
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).
