OPT-IN: First Measurement of Xiâ Polarization in Photoproduction

[Stepan Stepanyan]

- line 138, and caption of Fig.2, why invariant mass of cascade and pi- should line up at the lambda mass, bottom right distribution, how this can happen when cascade mass is larger than lambda mass?
- Eq.(1)  x_i are treated as independent variables, have you studied correlations, for example have you looked x_1 vs. x_2 distribution?
- line 174, polarization y-axis is isotropic in \phi, not in \theta, how acceptance effects can cancel 
- 178, did you check if the background is really unpolarized and does not have backward-forward asymmetry. For example did you looked at events on side bands
