# blackbody_lambda¶

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

Deprecated since version 4.0: BlackBody provides the same capabilities

Like blackbody_nu() but for $$B_{\lambda}(T)$$.

Parameters
in_xnumber, array_like, or Quantity

Frequency, wavelength, or wave number. If not a Quantity, it is assumed to be in Angstrom.

temperaturenumber, array_like, or Quantity

Blackbody temperature. If not a Quantity, it is assumed to be in Kelvin.

Returns
fluxQuantity

Blackbody monochromatic flux in $$erg \; cm^{-2} s^{-1} \mathring{A}^{-1} sr^{-1}$$.
