Here is an example. I do not know which part of the task failed but will dig into it.</p> <p><span class="image-wrap" style=""><img src="https://pfspipe.ipmu.jp/jira/secure/attachment/16160/16160_image+%281%29.png" style="border: 0px solid black" /></span></p> PIPE2D-1260

flux calibration vector is zero for medium resolution data

Task Normal Open Unresolved Masayuki Tanaka Masayuki Tanaka Wed, 19 Jul 2023 08:02:03 +0000 Thu, 27 Jul 2023 10:11:35 +0000 0 3 <p>The zero flux calibration vector was due to a stupid bug in my code, and it is actually non-zero. But, the flux-calibrated pfsSingle seems to show a discontiguity in the overall normalization between the b and m arms.</p> <p><span class="image-wrap" style=""><img src="https://pfspipe.ipmu.jp/jira/secure/attachment/16187/16187_image-2023-07-27-07-52-04-987.png" style="border: 0px solid black" /></span></p> <p>...and it is not clear the possible offset is due to flux calibration or something else.</p> <p>The normalisation spectra for <tt>b</tt> and <tt>m</tt> come from different exposures (taken at very different times), so I think that's expected.</p> <p>So, the offset is due to the way  (or when) the quartz spectra were taken? The offset is already there in pfsMerged. Note that the plotted are different objects from the plot above. <span class="image-wrap" style=""><img src="https://pfspipe.ipmu.jp/jira/secure/attachment/16188/16188_image-2023-07-27-08-19-38-100.png" style="border: 0px solid black" /></span></p> <p>That's right.</p> <p>We could/should use the brn data in conjunction with bmn to fix the normalisation of the m data. Do we need a separate ticket for that work?</p> <p>Yabe-kun told me that we took a set of bmn quartz data in this run. Perhaps new calibs from this run may solve the problem?</p> Relates PIPE2D-1251 Development Rank 0|zzsysv:
