The final coordinates will be what the fps will converge the cobras to.</p> <p>see more detail in <a href="https://pfspipe.ipmu.jp/jira/browse/INSTRM-1609" title="Calculate fibre positions in mm just before observing field" class="issue-link" data-issue-key="INSTRM-1609"><del>INSTRM-1609</del></a>.</p> INSTRM-1880 Add refraction correction routine in pfs_utils Task Normal Done Done Unassigned arnaud.lefur Fri, 3 Mar 2023 22:12:13 +0000 Sun, 25 Jun 2023 23:13:19 +0000 Sun, 25 Jun 2023 23:13:19 +0000 pfs_utils 0 2 <p>In the current sky-pfi transformation code, the atmospheric refraction is taken into account actually. (If the refraction is not taken into account, the fibers around FoV edge should have ~50–150um shift in EL axis.)</p> <p>Good !

I close this ticket.</p> Blocks INSTRM-1609 Development Rank 0|02qpjd:00r20060i2001864039 Sprint Eng12July
