<span>Here are my normalizations for MC and Data, asked about in the meeting.<br>

<div>Wab-beam-tri MC:<br>
</div>
<div>L_mc = (5e5 bunches)*(2500 e-/bunch)*(4.062e-4 cm target)*(6.306e-2 nuclei/(cm-barn))*(num_slic_files) <--- (=#recon_files*10)<br>
</div>
<div><br>
</div>
<div>Pair1 Data:<br>
</div>
<div>L_data = (("goodQ_atnom"e-9/1.6e-19)*(4.062e-4)*(6.306e-2))<br>
</div>
<div><br>
</div>
<div>Then 1000/L to get cross section in mbarns for the plots (just because it happens to be close to '1' for tritrig).<br>
</div>
<div>So for data, I actually use the reported "good" charge in the run wiki, not the reported luminosity, but they should be equivalent.
<br>
</div>
<div>Shown in the meeting: Run 7783, file 0 = 2939.405nC<br>

</div>
<div>The target thickness comes from an areal density of 0.00782 g/cm2 found here (via Clive):<br>
