Do the luminous intensities of LEDs mean the peak intensities of the LEDs, or the intensities averaged over different beam angles? 

Typically the data sheet of a LED specifies its luminous intensity and beam angle, like the following.

The data sheet says the intensity of the LED is between 150mcd and 200mcd. Would it mean that the intensity is 200mcd at the beam angle of 0 degree? Or is it the intensity averaged over entire beam angle?
