The next one is a counter example to the previous one. The one was strong diffusion case, here is an example which we identified with a weak diffusion case. First of all the morphology of radio w,r,t, the magnetic field was asymmetric,
	Suggesting a case of weak diffusion. Note the right foot-point has strong magnetic field than the other.  Second, the spectral hardening in the decay phase. If acceleration dominated, usually soft-hard-soft. That it it keeps hardening throughout the decay could mean that the electron dynamics were modulated by Coulomb collisions, as one possibility. This could be a weak pitch angle diffusion and in contrast with the previous example, which was found to be a strong diffusion.
