Cross-section, vector-polarization, and tensor-polarization distributions are calculated for the reactions 
and 
. Each reaction requires six characteristic functions that are bilinear in the, possibly complex, electromagnetic form factors, denoted 
and 
, of p and 
. For the hyperon reaction also the joint-decay distributions of and 
are calculated. Their knowledge allows a complete determination of the hyperon electromagnetic form factors, without measuring hyperon spins. We explain how this is done in practice. For some tensor-polarization components our results are in conflict with previously repeatedly published distributions.
