Confirm that this is real and fix the problem. Some plots are hopefully posted later.</p> PIPE2D-1330

Investigate the large scale feature of detectorMap offsets on detector

Task Normal Won't Fix Won't Fix Satoshi Hamano Kiyoto Yabe EDR Tue, 14 Nov 2023 04:42:59 +0000 Wed, 31 Jan 2024 20:06:46 +0000 Wed, 31 Jan 2024 20:06:46 +0000 0 3 <p>How are you measuring these offsets? Are they consistent with the measurements in the arcLines files?</p> <p>At the meeting, <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=shamano" class="user-hover" rel="shamano">Satoshi Hamano</a> said the positions are measured by fitting a Gaussian to the image, and then the offset is calculated as the difference with respect to the <tt>detectorMap&#95;used</tt>. However, I've been unable to reproduce these results (<a href="https://pfspipe.ipmu.jp/jira/browse/PIPE2D-1329" title="Individual fibers have significant offsets" class="issue-link" data-issue-key="PIPE2D-1329"><del>PIPE2D-1329</del></a>) with the arcLine measurements, so I think we need more information. <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=shamano" class="user-hover" rel="shamano">Satoshi Hamano</a> said he could provide his work as a script that we could run in the next couple of days.</p> <p>There are details in even Gaussian fitting. I think <a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=shamano" class="user-hover" rel="shamano">Satoshi Hamano</a> should take the lead on comparing his measurements with the arcLine files. It'd be good for him to look at some DCB data too, where crowding isn't an issue.</p> <p>If the code isn't pushed to GitHub (presumably to tickets/<a href="https://pfspipe.ipmu.jp/jira/browse/PIPE2D-1330" title="Investigate the large scale feature of detectorMap offsets on detector" class="issue-link" data-issue-key="PIPE2D-1330"><del>PIPE2D-1330</del></a>) that should be done as part of the delivery "as a script" &#8211; i.e. all the algorithmic parts should be in .py files in git.</p> <p>The offset problem has been solved in <a href="https://pfspipe.ipmu.jp/jira/browse/PIPE2D-1329" title="Individual fibers have significant offsets" class="issue-link" data-issue-key="PIPE2D-1329"><del>PIPE2D-1329</del></a> and the results are reasonably consistent with detectorMapQa, so I think we can close this ticket.</p> Relates PIPE2D-1329 Development Rank 0|02qph7:06r090i Sprint EDR+AIT
