== Orphaned references in [[:X-ray astronomy history]] ==

I check pages listed in [[:Category:Pages with incorrect ref formatting]] to try to fix reference errors. One of the things I do is look for content for [[User:AnomieBOT/docs/OrphanReferenceFixer|orphaned references]] in wikilinked articles. I have found content for some of [[:X-ray astronomy history]]'s orphans, the problem is that I found more than one version. I can't determine which (if any) is correct for ''this'' article, so I am asking for a sentient editor to look it over and copy the correct ref content into this article.

<b>Reference named "Gudel":</b><ul>
<li>From [[X-ray astronomy]]: {{cite journal |author=Güdel M |title=X-ray astronomy of stellar coronae |journal=Astron Astrophys Rev|year=2004 |volume=12 |page=71|doi=10.1007/s00159-004-0023-2 |url=http://astronomy.sci.ege.edu.tr/~rpekunlu/GBDG/papers/XRayfromStellarCoronae.pdf}}</li>
<li>From [[Stellar X-ray astronomy]]: {{ cite journal |author=Güdel M |title=X-ray astronomy of stellar coronae |journal=Astron Astrophys Rev. |year=2004 |volume=12 |pages=71–237 |doi=10.1007/s00159-004-0023-2 |url=http://astronomy.sci.ege.edu.tr/~rpekunlu/GBDG/papers/XRayfromStellarCoronae.pdf }}</li>
</ul>

I apologize if any of the above are effectively identical; I am just a simple computer program, so I can't determine whether minor differences are significant or not. [[User:AnomieBOT|AnomieBOT]][[User talk:AnomieBOT|<span style="color:#888800;">⚡</span>]] 05:34, 18 November 2009 (UTC)

References fixed in both articles. [[User:Marshallsumter|Marshallsumter]] ([[User talk:Marshallsumter|talk]]) 05:51, 19 November 2009 (UTC)

==Off topic==
The content below appears to be off topic so I moving it here for now:

''Section title:'' '''Detecting X-ray sources'''

As of 2000, there were about 220,000 known X-ray sources, with the vast majority discovered by the ROSAT X-ray satellite observatory.<ref name=Drake>{{cite web |author=Drake SA |title=How Many Known X-Ray (and Other) Sources Are There? |url=http://heasarc.gsfc.nasa.gov/docs/heasarc/headates/how_many_xray.html}}</ref>
