ssion&quot; case.

   The &quot;transmission&quot; light time correction yields the target's
   location as it will be when photons emitted from the observer's
   location at `et' arrive at the target. The transmission stellar
   aberration correction is the inverse of the traditional stellar
   aberration correction:  it indicates the direction in which
   radiation should be emitted so that, using a Newtonian
   approximation, the sum of the velocity of the radiation relative
   to the observer and of the
