It looks that the spot profile changes, which may be due to the difference of illumination. Firstly, please estimate how much PSF profile possibly changes with difference illuminations. Probably, we can start from two cases of extreme difference of illumination.</p> PIPE2D-1327

Estimate how much a spot moves if the illumination changes

Task Normal Open Unresolved Kota Hayashi Kiyoto Yabe EngRun donut Thu, 9 Nov 2023 23:37:52 +0000 Thu, 16 Nov 2023 01:21:29 +0000 0 2 <p>Here are some defocused model images of a single spot, with and without aberrations, in two extreme cases of illuminations. They have all actual aberrations unless specified as 'No Zernikes.' 'Center' and 'edge' illuminations here mean normal and upside-down Gaussians respectively, with a sigma being a fourth of the image size.</p> <p>  <span class="image-wrap" style=""><a id="16636_thumb" href="https://pfspipe.ipmu.jp/jira/secure/attachment/16636/16636_edge.png" title="edge.png" file-preview-type="image" file-preview-id="16636" file-preview-title="edge.png"><img src="https://pfspipe.ipmu.jp/jira/secure/thumbnail/16635/_thumb_16635.png" style="border: 0px solid black" /></a></span><span class="image-wrap" style=""><a id="16637_thumb" href="https://pfspipe.ipmu.jp/jira/secure/attachment/16637/16637_center_NZ.png" title="center_NZ.png" file-preview-type="image" file-preview-id="16637" file-preview-title="center_NZ.png"><img src="https://pfspipe.ipmu.jp/jira/secure/thumbnail/16636/_thumb_16636.png" style="border: 0px solid black" /></a></span><span class="image-wrap" style=""><a id="16633_thumb" href="https://pfspipe.ipmu.jp/jira/secure/attachment/16633/16633_edge_NZ.png" title="edge_NZ.png" file-preview-type="image" file-preview-id="16633" file-preview-title="edge_NZ.png"><img src="https://pfspipe.ipmu.jp/jira/secure/thumbnail/16637/_thumb_16637.png" style="border: 0px solid black" /></a></span><span class="image-wrap" style=""><a id="16633_thumb" href="https://pfspipe.ipmu.jp/jira/secure/attachment/16633/16633_edge_NZ.png" title="edge_NZ.png" file-preview-type="image" file-preview-id="16633" file-preview-title="edge_NZ.png"><img src="https://pfspipe.ipmu.jp/jira/secure/thumbnail/16633/_thumb_16633.png" style="border: 0px solid black" /></a></span></p> <p>Turning off the centering process on creating model images, I checked three different spots to see how much in-focus images move when using non-uniform illuminations. For the 'center' and 'edge' cases, the differences (in pixels) from the uniform illumination case were as follows.<br/> without aberrations ('center', 'edge'):<br/> <span class="error">&#91;-0.00489392, -0.0002655 &#93;</span>, <span class="error">&#91;0.00408945, 0.00090781&#93;</span><br/> <span class="error">&#91;-0.00054981, -0.001028 &#93;</span>, <span class="error">&#91;0.00048404, 0.00100647&#93;</span><br/> <span class="error">&#91;-0.00135586, 0.00247819&#93;</span>, <span class="error">&#91;0.00164713, -0.00104468&#93;</span><br/> with aberrations ('center', 'edge'):<br/> <span class="error">&#91;-0.05716209, 0.04843167&#93;</span>, [ 0.04769489, -0.04080947]<br/> <span class="error">&#91;-0.07478676, 0.0367169 &#93;</span>, [ 0.06002609, -0.03209267]<br/> <span class="error">&#91;-0.03818032, 0.10790845&#93;</span>, [ 0.03467106, -0.09408475]</p> Development Rank 0|02qpjd:00r20060i200186403c0309
