Dear Stepan, 
<div><br>
</div>
<div> These are good comments, thank you. </div>
<div><br>
</div>
<div>@Nicolas:  It may be better to eliminate the entire sentence starting with “To achieve this” because it is getting too deep into the analysis, and much more information is needed to understand what is written in that sentence. </div>
<div><br>
</div>
<div>@Nicolas: I could also suggest that you replace “Before normalization” with “Before normalizing the pion energy distribution to unity to perform a shape analysis,…” or put this kind of phrase *after* the sentence that mentions the acceptance correction.
 The term “shape analysis” I think is pretty standard.<br id="m_-1401108216681402389lineBreakAtBeginningOfMessage">

<div> @Nicolas: The data used were from the CLAS EG2 dataset.</div>

<div>I am not sure I understand the text. It is not clear what this is about. 
<div>- what means “a kinematic variable that helps isolate positive pions”?</div>
<div>- what gets normalized? Are we talking about the ratio of energy spectra on heavier targets to deuterium? </div>
<div>- phrase “energy distribution if the targets” is incorrect, I assume. </div>
<div>- should mention which data from the CLAS detector are used</div>

</b>Our objective is to test published models of partonic energy loss, particularly those describing the energy loss mechanisms of quarks traversing nuclear matter, within the framework of DIS. Our methodological approach focuses on quantifying quark energy
 loss in cold matter by analyzing positive pions produced in various nuclear targets, including Deuterium, Carbon, Iron, and Lead. To achieve this, we define a kinematic variable that helps isolate positive pions produced outside the nucleus. Before normalization,
 we perform acceptance corrections to account for the detector's efficiency and ensure accurate comparison of the spectra. By normalizing the energy spectra of positive pions produced from these distinct targets, and based on the BDMPS theory, which posits
 that quark energy loss depends only on nuclear size, we assume that the energy distributions of the targets will exhibit similar behavior. For this normalization, we identify an energy shift between these distributions, corresponding to the quark energy loss.
 To ensure accuracy, we employ statistical techniques such as the Kolmogorov-Smirnov test. To validate our methods, we used a preliminary dataset collected using Jefferson Lab's CLAS detector.</span></p>
