Do we see bright blue spots at double their original wavelength, i.e., in red

We have to use HgCd because other lamps do not have basically any lines below 490nm, which is the upper limit for this analysis. As such I can operate only with calexp images (<a href="https://pfspipe.ipmu.jp/jira/browse/PIPE2D-935" title="Support HgCd and other multi and single element sources" class="issue-link" data-issue-key="PIPE2D-935"><del>PIPE2D-935</del></a>). I have attached two figures</p> <p>1. blue_arm.png showing the spots at the blue end of blue arm. Both of these lines are quite strong (see the bar on the images).<br/> 2. red_arm.png shows the cutouts of the calexp file at the wavelengths of the spots in the blue arm multiplied by 2. I do not see any appreciable contribution to the flux from the ghosts.  <span class="image-wrap" style=""><a id="14468_thumb" href="https://pfspipe.ipmu.jp/jira/secure/attachment/14468/14468_red_arm.png" title="red_arm.png" file-preview-type="image" file-preview-id="14468" file-preview-title="red_arm.png"><img src="https://pfspipe.ipmu.jp/jira/secure/thumbnail/14467/_thumb_14467.png" style="border: 0px solid black" /></a></span><span class="image-wrap" style=""><a id="14468_thumb" href="https://pfspipe.ipmu.jp/jira/secure/attachment/14468/14468_red_arm.png" title="red_arm.png" file-preview-type="image" file-preview-id="14468" file-preview-title="red_arm.png"><img src="https://pfspipe.ipmu.jp/jira/secure/thumbnail/14468/_thumb_14468.png" style="border: 0px solid black" /></a></span></p> Relates INSTRM-1470 Development Rank 0|zzsgv3: Story Points 1.0
