This is found mainly in 600-700 nm in red arm, but rarely in blue arm. The boxy feature is found in 3 fibers of 85 FLUXSTD fibers in visit 82596. These features are not always in the same fiberIds in a different visit. They are seen both in pfsMerged and pfsArm. The normalization is smooth in these problematic wavelengths.</p> <p><span class="image-wrap" style=""><img src="https://pfspipe.ipmu.jp/jira/secure/attachment/15500/15500_gatagata_merged_82596.png" height="180" width="364" style="border: 0px solid black" /></span></p> <p> </p> <p>Hamano-san found that the problematic fibers have a bright fiber next to them. The boxy features could be leaks from those bright fibers.</p> <p><span class="image-wrap" style=""><img src="https://pfspipe.ipmu.jp/jira/secure/attachment/15499/15499_calExp_v82596_1r_crosscut_v49_fID6.png" height="172" width="221" style="border: 0px solid black" /></span></p> <p>There are upturns at the sides in fiberprofile, which could cause this issue. </p> <p><span class="image-wrap" style=""><img src="https://pfspipe.ipmu.jp/jira/secure/attachment/15498/15498_fiberprofile.png" height="189" width="260" style="border: 0px solid black" /></span></p> <p> </p> PIPE2D-1151
