OPT-IN: First Measurement of Xiâ Polarization in Photoproduction

[Daniel Carman]

Dear Jason, Lei, and Brian,

I have read through the draft of your paper on cascade polarization in
photoproduction reactions from a proton target dated March 3. My comments
are included below. If you have any questions, let me know.

Regards,
Daniel

 - Fig. 2. What is plotted in the LR plot? The invariant mass of the cascade- and pi-
   cannot give a peak at 1.12 GeV. What am I missing here?
 - Fig. 2 caption. Line 7. You describe the parameters M and sigma, but there are no
   fit parameters given in the figures.
 - Line 87. Use "pseudo-randomly".

   this data sample as well as the CLAS data set that these data came from.
