[Clascomment] OPT-IN: Measurement of the nuclear multiplicity ratio for K0s hadronization at CLAS

[Raphael Dupre]

Knowing that the statistics from iron ~2.5 times larger than that from lead, I am puzzled by your statistical error bars, which are comparable for the two targets (figure 4).

Page 6 line 9, you have indicated that you applied the acceptance correction without specifying details. Could you add a sentence or two to explain more since you are using double ratios? In your analysis note (part II.I) you seem to omit the acceptance correction of the electrons for the normalization factor in the multiplicity ratio. However recent analysis of the same eg2 data (http://www.jlab.org/~mineeva/lepto/accCompar.html) shows a significant effect of about 10-15%. Did you include this effect in the final errors?

For the acceptance correction to Ks, you use one dimensional binning, this method is fine when your simulation reproduce very well the data. However, the figure 1 and 3 of your reply to round 4 (http://www.jlab.org/Hall-B/secure/nuclear/eg2_k0/reply_to_round4.pdf) show that a significant discrepancy exist between the two. This seem to indicate the need for a multi-dimensional binning for the acceptance correction. Could you clarify this?
