[Clascomment] OPT-IN:Multidimensional Measurements of Beam Single Spin Asymmetries in Semi-inclusive Deep-inelastic Charged Kaon Electroproduction off Protons in the Valence Region

[Volker Burkert]

Hello lead authors,

 before I begin with the review of the text I like to ask that you fix the following  12 references: 
14, 15, 16, 17, 18, 19, 20, 34, 35, 36, 38, 39. 
They are either incomplete or have only acronyms for the author(s). 

Thank you,
Volker
