This is a very nice paper representing a lot of work, and I have only a couple of minor comments:

1) The title and abstract refer to Sigma^+(1385) but the reaction is shown as gp->K^0Sigma^*+.  I assume Sigma^+(1385) and Sigma^*+ are the same baryons. To avoid some confusion chose one notation for it.  The remainder of the paper uses Sigma^*+, so the best would be to introduce the state in the abstract as Sigma^*+(1385) and use Sigma^*  from there on. 

2) The significant figures in the abstract for the partial width is given as 250 and the error is given as 56.9 ...  The main result should have the same significant figure, e.,g. 250.x +/- 56.9 . Similar for some entries in table III, e.g. 0.012+/-0.0024 and 0.040+/-0.0057. 
 
3) In general, many intermediate results in the tables are given with too many significant figures, and could be reduced by one figure. It would improve readability.
