  Analytical radiative corrections of order (alpha/pi)(q/M) are calculated for
the four-body region of the Dalitz plot of baryon semileptonic decays when the
s1.l correlation is present. Once the final result is available, it is possible
to exhibit it in terms of the corresponding final result of the three-body
region following a set of simple changes in the latter, except for a few
exceptions. We cover two cases, a charged and a neutral polarized decaying
baryon.
