# blackbody_nu¶

astropy.modeling.blackbody.blackbody_nu(in_x, temperature)[source] [edit on github]

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. flux : Quantity Blackbody monochromatic flux in $$erg \; cm^{-2} s^{-1} Hz^{-1} sr^{-1}$$. ValueError Invalid temperature. ZeroDivisionError Wavelength is zero (when converting to frequency).
