The measured flux is different from the object’s true inherent brightness, called its luminosity.
NettetBrightness temperature or radiance temperature is the temperature at which a black body in thermal equilibrium with its surroundings would have to be in order to duplicate the observed intensity of a grey body object at a frequency .

Nettetbrightness, in physics, the subjective visual sensation related to the intensity of light emanating from a surface or from a point source (see luminous intensity).
NettetBrightness, which is also referred to as brilliance, is an expression of the relative intensity of the energy output of a visible light source. It can be expressed as a total energy value, which is different for each of the curves in the Figure 2. Another way to express brightness is the amplitude of the wavelength where the intensity is greatest.
