This requires a set of lines similar to the ArNeKrXe ones; we can start with the Rousselot OH list (Rousselot, P. et al. (Feb. 2000) A&amp;A 354, pp. 1134–1150) and Patat, F. (2008). A&amp;A 481, 575–591 (2008) <a href="https://www.aanda.org/articles/aa/pdf/2008/14/aa9279-07.pdf" class="external-link" rel="nofollow">https://www.aanda.org/articles/aa/pdf/2008/14/aa9279-07.pdf</a></p> <p>This ticket is to generate a file in the proper format. There will be another to validate the line lists by comparison with real PFS spectra (which we now have!)</p> PIPE2D-732

Generate an "arc" line file containing night sky lines such as 5577 and OH

To be downloaded and placed under git.</p> <p>For Patat (2008), the night sky <em>spectra</em> (as opposed to line list), are available here: <a href="http://www.eso.org/~fpatat/science/skybright" class="external-link" rel="nofollow">http://www.eso.org/~fpatat/science/skybright</a> . The list of OH lines does not seem to be available in machine-readable form. Investigating further. </p> <p>I don't think we need machine-readable Patat. Almost all the lines are in the Rousselot list, and Patat will help us identify the other lines (there are other references).</p> <p>Let's start with these two sources and get the line lists into the system.</p> <p>[ I thought we already had that Rousselot file somewhere, but really wanted one annotated with the transitions? And that someone had <em>that</em> list available. ]</p> <p>I took a quick look at your new version – looks much better.  Thanks for fixing the OI wavelengths.</p> <p>Please change the 557.8887 intensity to say 100</p> <p>The OH lines are visible above a quoted intensity of c. 0.40.  There are a lot of doublets with the identical intensity and splittings of c. 0.003nm, e.g.</p> <div class="code panel" style="border-width: 1px;"><div class="codeContent panelContent"> <pre class="code-java"> 724.68910 2.657e+00 OH 0 # [5] 724.69160 2.657e+00 OH 0 # [5] </pre> </div></div> <p>Please merge these into a single line with the average wavelength (and do NOT label it as a blend &#8211; add a new flag if we need one). They must be a transition to a split lower state, so the intensity ratio will be stable and this is OK. No need to do the ones with intensity &lt; 0.10</p> <p>There are other obvious blends, but let's get these issues cleaned up first.</p> <p>I've done the work for this. Stand by for a push once I've gone through and checked for other problems.</p> <p>Effectively reviewed by RHL and Price, so elect to skip a formal PR in this instance.</p> <p>Who is going to merge this?</p> <p>I am.
