That is, if we delete delta E, it necessarily follows that gamma is a
function of launch angle.

Hi Carl,
I would contend that the TPT article did not prove that gamma is
independent of the launch angle (even within the erroneous equation 1).
On the contrary, when the derivatives of R were calculated (with respect
to the launch angle), gamma was simply ASSUMED to be a constant.
