<br></div><div>I had a number of mostly minor comments on the proposal, which I've included below. Along with them comes a few questions:</div><div>
In 2 The Proposed Experiment (page 19), first paragraph, do we want the x range to be the central values we're measuring or also include the x range we're average over? If the former, then it should be 0.16 < x < 0.49. If the latter, then it should be 0.09 < x < 0.58.</div>
<div><br></div></div></blockquote><div><br></div><div>ok, I've updated to the former.</div><div><br></div><div> </div><blockquote class="gmail_quote">
<div><div></div><div>Figure 7: I don't have the colors or legend of the different models -- is this something you'd like back in? I think the coloring I would argue against, since what we want to emphasize "pops" more without it. However, I leave this to the collaboration. Relatedly, I'm currently plotting b1 vs x. As Patricia noted, our error bars (as well as HERMES) would look drastically smaller if we plotted x*b1 vs x. Which method is preferred?</div>
<div><br></div></div></blockquote><div><br></div><div>It's fine without color, but let me know which curve is which and I'll add it to the caption. (However, the 2 curves for Azz have same style.)</div>
<div><br></div><blockquote class="gmail_quote"><div><div></div><div>
Table 4 (page 24) -- Does this need to be updated since we're looking at 30 days instead of 28?</div><div><br></div></div></blockquote><div><br></div><div> The diff between 28 and 30 on the overhead is small. </div>
<div><br></div><div> </div><blockquote class="gmail_quote"><div><div></div>
<div>Take care,</div><div>Ellie</div><div><br></div><div>And now, my comments.</div>
<div>---------------------------------------------------</div><div><br></div><div>Forward, second paragraph (page 4): "…sensitivity of the integrated counts in each states…" to "…sensitivity of the integrated counts in each state…"</div>
<div><br></div></div></blockquote><div>ok </div><blockquote class="gmail_quote"><div>
<div></div><div>Figure 4 (page 14), the left plot looks extremely light when viewed on the iPad, but looks fine on my Mac. My guess is it's fine, but I don't have my printed copy available and just wanted to double-check that it will look fine printed. If not, I can darken the lines a bit. Figure 6 (both plots) do the same thing.</div>
<div><br></div></div></blockquote><div><br></div><div>yes, these plots are stolen from some old publications. Please do whatever you can to improve.</div><div>
<br></div><div> </div><blockquote class="gmail_quote"><div><div></div><div>
Table 2 (page 19) maybe should be re-captioned to read "Expected uncertainties in Azz and b1."</div><div><br></div></div></blockquote><div>ok</div><div>
</div><blockquote class="gmail_quote"><div><div></div><div>

<div><br></div><div>In 2 The Proposed Experiment (page 19), second paragraph, the dilution factor being used is 0.95*f_ideal = 0.285. Also our luminosity comes out to 1.57x10^35/cm^2*s -- Using 2 is probably fine, I don't know how many digits we want in it. Also the HMS omega acceptance we've been using is 5.6 msr, not 6.5. In the last sentence, the projected uncertainties are shown in Table 2, the kinematics of the spectrometers in Table 1.</div>
<div><br></div></div></blockquote><div>ok, fixed</div><div> </div><blockquote class="gmail_quote">

<div><br></div><div>Figure 7 (again): We don't have a black band representing systematic uncertainty, the plots I made only show statistical. </div>
<div><br></div></div></blockquote><div><br></div><div>ok, I removed the text. We'll need a plot with syst on eventually.</div><div><br></div><div> </div><blockquote class="gmail_quote">
<div><div></div><div>In 2.1 Experimental Method (page 22), paragraph 5 (top line of page 22), there is an extra "and" in "…number of deuterium nuclei in the target and and…" In the same paragraph, a super minor question is whether ND3 and LHe should be italicized or not. In the following paragraph, just after Equation 22, we should say R_T is the total rate since we're no longer using R_D in Equation 22.</div>
</div></blockquote><div><br></div><div>ok, fixed</div><div> </div><blockquote class="gmail_quote"><div><div>
<br></div><div>In Time dependent factors (page 23), paragraph 4, it reads "The signal with noise ratio suppression…" when it should read "The signal to noise ratio suppression…"</div>
</div></blockquote><div><br></div><div>ok, fixed </div><blockquote class="gmail_quote"><div><div>
<br></div><div>Table 4 (page 24) -- Does this need to be updated since we're looking at 30 days instead of 28?</div><div><br></div></div>
</blockquote><div>nope, unless someone has updated estimates </div><blockquote class="gmail_quote"><div><div>
</div><div>In 2.2 Polarized Target (page 24), first paragraph, do we want to mention that it's an ND3 target?</div><div><br></div></div>
</blockquote><div>ok</div><div> </div><blockquote class="gmail_quote"><div><div>
</div><div>Figures 10 (page 25) and 11 (page 26) -- Is the GeN mentioned the neutron electric form factor? If so, it's normally written G_E^n. If it's not, I apologize for pointing it out.</div>
<div><br></div></div></blockquote><div>yes. but we usually call E08-027 "g2p" for example</div><div> </div><blockquote class="gmail_quote">
<div><div></div><div>In 2.2.1 Polarization Analysis (page 27), paragraph 5 (first full paragraph on page 27), if LHe and ND3 on page 22 are italicized than ND3 and LiD here should be as well. It also has GeN, similar to Figures 10 and 11. Another super-minor point, in the last paragraph in the section (page 27, second full paragraph) 'hole-burning'. should be written as "hole-burning." (according to my husband who majored in English)</div>
<div><br></div></div></blockquote><div>ok </div><blockquote class="gmail_quote"><div>
<div></div><div>In 2.2.2 Depolarizing the Target, first paragraph (page 27), a comma should be inserted after "To move from polarized to unpolarized measurements" and another one should be added in the second paragraph after "To minimize [a] systematic effect over time"</div>
<div><br></div></div></blockquote><div>ok</div><div> </div><blockquote class="gmail_quote"><div>
<div></div><div>In 2.2.3 Rendering Dilution Factor, first paragraph (page 27), a comma should be inserted after "To derive the dilution factor" In the line following it, the and should be removed from "…measured, and neglecting the small contribution…"</div>
<div><br></div></div></blockquote><div>ok</div><div> </div><blockquote class="gmail_quote"><div>
<div></div><div>In Equation 33, the second line has "…3sigma(1+2AzzPzz/2))pf + …" -- should that 2 before Azz be there? I think it's an extra factor that doesn't continue with the rest of the derivation.</div>
<div><br></div></div></blockquote><div>I'm not sure. </div><blockquote class="gmail_quote">
<div><div></div><div>In 3 Summary, first paragraph (page 28), "We request 28 days of procution…" should be changed to "We request 30 days of production…" The comma in "…using a longitudinally polarized deuteron target, together with…" should be removed. In the second paragraph, the comma in "…to the tensor quark polarization, and allow a test of…" should be removed.</div>

<div><br></div><div>There is some lagtime for implementation, but I think this reflects pretty well where our discussion was about 24 hours ago. However, we still need:</div><div><br></div><div>-updated rates/kin plots from Ellie or Patricia and values for the table</div>
