I have noticed that page 7 of the document cited mentions the "Lamor formula" [sic]. I believe that the notation shown is actually the Larmor formula (in fact, its Lorentz invariant form). Yes, sad I know.

Anyone like to have a stab at the units in SI?

Sir Joseph Larmor FRS FRSE (1857 - 1942). Hendrik Lorentz ForMemRS (1853 - 1928).

If you don't inspect ... don't expect.
