[Clascomment] OPT-IN:Suppression of neutral pion production in deep-inelastic scattering off nuclei with the CLAS detector

[David Ireland]

Hi Taisiya, et al.,

Well done for getting the paper to this stage. These are interesting results, and point the way to more potential research.

Since I was partially responsible for suggesting the presentation of the figures (and all due respect to Daniel!), I'd like to defend your presentation. There are many guides on using color in plots, but one example is in:

https://seaborn.pydata.org/tutorial/color_palettes.html

The two important messages in that piece are: "Vary hue to distinguish categories", and in your case the different targets correspond to different categories;  "Vary luminance to represent numbers", and in figure 2, the (numerical) bins in z are those numbers that need to be represented (in addition to the dependence on p_T^2). You have followed these guidelines. There are of course an infinite set of color pallettes to use for either variation, so the choice is in the eye of the beholder.

As to figure 3, to my mind the heterogeneity of the symbols actually serves to illustrate the commonality in values of the multiplicity ratio for a variety of different kinematics. The fact that they all cluster around well defined values for each target at each value of z is a visual indication that there is an effect that appears to be largely independent of the kinematics.

Please include "the UK Science and Technology Facilities Council" in the acknowledgments, but I should point out that there should be (at least used to be) a standard template of acknowledgments for various funders that can be found in the file generated in the opt-in process. 

Cheers,

Dave
