Thanks for including TOF time resolution results in your talk (though I don't see the slide in the file linked from agenda - can you upload the updated version please?)</div>

To follow up on discussion from Monday RGH meeting, I have looked at the time resolutions again using a 3 mm x 3 mm sensor in simulation.</div>
<div class="elementToProof" style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
The resolution results are shown in slide 2 of the attached.</div>

Also, the resolution values shown on Monday using scaling by cross section to 3 mm x 3 mm area are consistent with the values from 3 mm x 3mm sensor (slide 3)</div>

I also see a trend of resolution getting poorer as the threshold number of photons increases.</div>

It's not clear to me yet whether we need to scale the results by sqrt(2) to compare with the PANDA measurements.</div>
