 +Shen & Zhang 09 paper 2009, MNRAS 398, 1936 shows that (1) Synchrotron can have the same appearance at gamma, X, but very different manifestations at optical, in four cases. This is the most recent treatment, those below are listed for hisotrical interest.   (2) the same paper shows that incredible information, lorentz factor, radius of emission, and B are encoded in the self-absoption frequency (so go measure it!).
