Holly, can you confirm? Also, the minimum allowed theta for the pion (which should be parallel to the virtual photon) is 7.5 degrees, so I analytically determined the values of the electron kinematics that would make the virtual photon be 7.5 degrees and used that for the last point. </div><div class="gmail_default" style="font-size:large"><br></div><div class="gmail_default" style="font-size:large">I calculated the new runtimes based on an interpolation between points in the previous version of the table, assuming that the amount of time needed to obtain a given amount of data scaled as e^(const*Q^2), and that the precision scales as 1/time^2 for a given Q^2. I then rounded some of these values to multiples of 0.5 hours, but I can change that back to the un-rounded values. I used the values obtained before adding additional time in each case. </div><div class="gmail_default" style="font-size:large"><br></div><div class="gmail_default" style="font-size:large">Best regards,</div><div class="gmail_default" style="font-size:large">Sebouh</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Nov 10, 2025 at 5:52 PM Carlos Ayerbe Gayoso via Color_transp <<a href="mailto:color_transp@jlab.org" target="_blank">color_transp@jlab.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div>

I was scaling my table <a id="m_8690307278154469933m_2801376292068514854OWA97dc5ace-d5e2-7083-2b41-3719e4f222b1" href="https://urldefense.proofpoint.com/v2/url?u=https-3A__docs.google.com_spreadsheets_d_1R3pbuDNsrS3M-2DSAq8H1cNxVUEVzxr4vKOxGhfE1ATqA_edit-3Fusp-3Dsharing&d=DwMFaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=XtVl8BY42jbbWh0Vu1ygqgFBYEJMENirtKAh3P_9ayw&m=658ZEEoo1eRdTBz9_rxWxlVUfVAlyG52JpQDuE0jbeXXWJjj7ylSV2swm-ZYY64W&s=0JbhiaiuPfAm0qTQUh2o9fmdRIFMHTDqqC1P0Qh1KJs&e=" target="_blank">

the dependence is not linear (I just plotted them to observe the shape). </div>

I also updated the kinematic table in the run plan, and comparing with Sebouh's, both scripts behave similar, except for 8.5 which it differs, unless, t=-0.48 (in my case). It is just an anecdote, I trust in Sebouh's script better than mine. </div>

The only question I have about the new table is if the uncertainty is based in the new run times, original or with the extras. When I was calculating the numbers, in order to achieve the uncertainty in the proposal, should be considered only the original time,
and not the extras (like 2 and not 2x3 for 1H or 2.5 and not 2.5+6 for 12C). </div>

Then is the 20% extra suggested by Dipangkar... I forgot, but that 20% is extra data taking to compensate multi-pions isn't it? How affects the total run numbers? (time, events)</div>
