Since the curves overlap, the scattered light scales with the number of active fibers.</p> <p><span class="image-wrap" style=""><img src="https://pfspipe.ipmu.jp/jira/secure/attachment/15621/15621_scaling.png" width="900" style="border: 0px solid black" /></span></p> <p>Background models constructed from mod32 exposures:</p> <p><span class="image-wrap" style=""><img src="https://pfspipe.ipmu.jp/jira/secure/attachment/15635/15635_backgrounds-mod32.png" width="900" style="border: 0px solid black" /></span></p> <p><a href="https://pfspipe.ipmu.jp/jira/browse/PIPE2D-1244?focusedCommentId=33996&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-33996" class="external-link" rel="nofollow">Devised an experiment</a> to measure the backgrounds with different input spectra in the next run.</p> Development Rank 0|02qph7:06r1
