This zoom shows the blue part of the red detector, where the subtraction is better.

I see few problem, but I have to do a full analysis and I will report here on the problems that I encounter. </p> <p>I have uploaded yesterday the presentation (Summary_v1.pdf) with examples of several types of issues that I have encountered. I will update this pdf periodically. After discussion (Monday Princeton meeting?) I plan to open tickets regarding the issues that I have noticed.</p> <p>This ticket has been successfully completed. In the meantime, we have identified a number of issues, for which tickets have been issued (<a href="https://pfspipe.ipmu.jp/jira/browse/PIPE2D-883" title="Optimize continuum subtraction for sky data" class="issue-link" data-issue-key="PIPE2D-883">PIPE2D-883</a> to <a href="https://pfspipe.ipmu.jp/jira/browse/PIPE2D-885" title="Fiber trace throughput should not be applied to 2d sky psfs" class="issue-link" data-issue-key="PIPE2D-885">PIPE2D-885</a>). </p> Blocks PIPE2D-793 PIPE2D-874 Development Rank 0|02qpq3:r2m Story Points 4.0
