OPT-IN: Differential cross sections and polarization observables from the CLAS Kâ photoproduction and search for new Nâ states

[Volker Burkert]

This is a nice letter with interesting results. 

I have only two comments, one is on the sentence in the introduction: 
" The N(1710)½+ is clearly seen in gp-> KLambda while it is controversially discussed 
in piN scattering" This is no longer the case, the new RPP 2016 will show the N(1710) as 
a 4* rated states with 4* also in pi-N. This is in part related to the new results from 
D. Roenchen et al., where they need the state in pi-N. Previous analysis by GWU
had parameterization that averaged over the structure seen by the new analysis. 

A second comment is, that you include the data points in the CLAS physics 
data base and make reference to it.
