Hi Peter,</div>

Slide 5, Advantage of lower energies, "double statistics with 3 weeks of running" , Not clear what it is doubling from. Also the plot with result projections does not correspond to the lower energy results, are you planning to update this ? </div>

On the toy slides I would make clear what the generated value of alpha was.</div>

The statement about the reduced linear polarisation bias is not really made from these toys. The proposal extraction is within 1 sigma of the generated value, while the new value is just over, all be it with much reduced statistical uncertainty. This really
needs fits with free linear polarisation. I think the main conclusion of the exercise is the sensitivity to alpha is greatly increased with the lower energy amplitudes.</div>

<div class="x_PlainText">Hi all,<br>
<br>
As we discussed in our last meeting there will be a special Physics WG meeting tomorrow to focus on proposals for low energy running.<br>
<br>
I produced a few preliminary studies to show how helpful it can be to our measurement. The short answer: it looks like it could be extremely helpful.<br>
<br>
Attached are the slides I intend to show tomorrow. There will be some changes as I am still running more fits in different configurations but the main takeaway will not change much.<br>
I will also add a little bit more text to the result slides to make them easier to understand for people who cannot attend but will look at slides later on. That being said I wanted to send these out to you before I show them and there is not much time left
until the meeting. So here is the current state...<br>
<br>
Let me know if you want me to make any changes.<br>
<br>
Cheers,<br>
Peter<br>
