<div>Hi astropyers,<br>
</div>
I have a ready made spectral line atlas. Is there a
direct way to mark the spectral lines in one spectrum
plot?<br>
I have found a module called lineid_plot. However,I can
not install it. <br>
<br>
The images below are three examples.<br>

<p style="margin: 1.2em 0px ! important;">I usually do this by
reading my lines into a dict of the form <code
style="font-size: 0.85em; font-family:
Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em;
padding: 0px 0.3em; white-space: nowrap; border: 1px solid
rgb(234, 234, 234); background-color: rgb(248, 248, 248);
border-radius: 3px 3px 3px 3px; display: inline;">{'Line
Name': wavelength}</code> and then using a code snippet like
this:</p>
<pre style="font-size: 0.85em; font-family: Consolas,Inconsolata,Courier,monospace;font-size: 1em; line-height: 1.2em; overflow: auto;margin: 1.2em 0px;"><code style="font-size: 0.85em; font-family: Consolas,Inconsolata,Courier,monospace;margin: 0px 0.15em; padding: 0px 0.3em; white-space: nowrap; border: 1px solid rgb(234, 234, 234); background-color: rgb(248, 248, 248); border-radius: 3px 3px 3px 3px; display: inline;white-space: pre; border-radius: 3px 3px 3px 3px; border: 1px solid rgb(204, 204, 204); padding: 0.5em 0.7em;display: block; padding: 0.5em; color: rgb(51, 51, 51); background: none repeat scroll 0% 0% rgb(248, 248, 255);" class="language-python"><span style="color: rgb(51, 51, 51); font-weight: bold;" class="keyword">for</span> theline <span style="color: rgb(51, 51, 51); font-weight: bold;" class="keyword">in</span> MWlines.keys():
ax.axvline(

ax.annotate(
theline+<span style="color: rgb(221, 17, 68);" class="string">' MW'</span>, (MWlines[theline]-<span style="color: rgb(0, 153, 153);" class="number">.0</span>, <span style="color: rgb(0, 153, 153);" class="number">2.2</span>),

horizontalalignment=<span style="color: rgb(221, 17, 68);" class="string">'center'</span>, color=<span style="color: rgb(221, 17, 68);" class="string">'grey'</span>)</code></pre>
<p style="margin: 1.2em 0px ! important;">This will of course be
varied slightly depending on the context, but that’s the basic
idea.</p>
