Create high signal-to-noise spectra of calib lamps

Task Normal Done Done ncaplar ncaplar Tue, 30 Nov 2021 19:51:12 +0000 Mon, 7 Mar 2022 14:02:41 +0000 Thu, 10 Feb 2022 15:06:31 +0000 0 2 <p>I have created the spectra for our lamp lines at Subaru. The visit used are:</p> <p>Krypton - from visits 71155, 71156, 71157<br/> Argon - from visits 71162, 71163, 71164<br/> Xenon - from visits 71159, 71160, 71161<br/> Neon - from visits 68640, 68641, 68642<br/> Hgcd - from visit 67757<br/> Haloen - from visit 68087</p> <p>I generate the lines by using interpolateFlux (from from pfs.drp.stella.interpolate) to interpolate all fibers from an exposure to the same grid. I then calculate mean out of all of the interpolated fibers, from all of the avaliable exposures. I normalize the flux to 1 second, by dividing the data by the effective exposure time. </p> <p>I have also created csv files, which I have shared with JEG.</p> <p>Hassan can you please check that you can load pandas files and that they look reasonable?</p> <p>What was the quality of the wavelength solutions?</p> <p>Sent to JEG for his comments. Still working with him to understand if he is satisfied with the analysis I did.</p> <p><a href="https://pfspipe.ipmu.jp/jira/secure/ViewProfile.jspa?name=price" class="user-hover" rel="price">price</a> Can you perhaps elaborate? To get spectra I ran <tt>reduceExposure</tt>, and then interpolateFlux on <tt>pfsArm.flux</tt> arrays. See November 11, 2021 discussion in zoom chat with me, you and Hassan. I ran <tt>reduceExposure</tt> because <tt>reduceArc</tt> does not succeed for all arclines (if there are no lines on r or b detector for that particular arcline), so I wanted to be consistent across all detectors and lines. I have a felling that you would do something much differently? </p> <p>Did <tt>reduceExposure</tt> use the <tt>adjustDetectorMap</tt> feature? If so, what did it report as the quality of the fit?</p> <p>No, because it fails when there are not enough lines (fails in <tt>doAperatureCorrection</tt> ) step. Typical command I have used is: </p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> reduceExposure.py /projects/HSC/PFS/Subaru --calib /projects/HSC/PFS/Subaru/CALIB-PFI-20211220/ --rerun ncaplar/PIPE2D-953 --id visit=71155 -j 20 -c isr.doFlat=False doAdjustDetectorMap=False photometerLines.doApertureCorrection=False --clobber-config </pre> </div></div> <p>Paul, I reran with  <br/> <tt>doAdjustDetectorMap=True photometerLines.doApertureCorrection=False</tt><br/> and these are summary results at the end of processing. Find results in the gist below. Is that what you had in mind?</p> <p><a href="https://gist.github.com/nevencaplar/cdf761414ddd7febf42dc541ea49d01a" class="external-link" rel="nofollow">https://gist.github.com/nevencaplar/cdf761414ddd7febf42dc541ea49d01a</a></p> <p>That's good, thanks.</p> <p>I am currently waiting for comments by Jim if the format I have provided is acceptable to him. If he does not get back to me I will ask him on Monday meeting. I have also rerun everything with <tt>doAdjustDetectorMap=True</tt>, and changes are minor. If Jim gives ok, I will upload the final version and close.</p> <p>I have talked with Jim today. He is fine with the format and information contained, he only wants the continuum (halogen) lamp to be added to the mix.</p> <p>Added another version. The difference from last attempt is: </p> <p>1. Continuum added <br/> 2. Pipeline ran with detectorMap being adjusted using lines from each lamp. Makes minimal differences to the actual result.</p> Relates PIPE2D-998 Development Rank 0|zzsh26:zw Reviewers hassan Sprint 2DDRP-2021 A12 2DDRP-2022 A Story Points 2.0
