Addendum to "radiative corrections to the Dalitz plot of semileptonic decays of neutral baryons with light or charm quarks"

We show that the radiative corrections containing terms up to order q/M1 for unpolarized semileptonic decays of baryons with positron emission can be obtained by simply reversing the sign of the axial-vector form factors in the corresponding final expressions of such decays with electron emission. This rule is valid regardless of the final kinematical variables chosen and of the particular Lorentz frame in which the final results are required.
