Re: [arts-users] Temperature Retrievals of Oxygen emission lines with Zeeman effect and line mixing
Dear Witali, since these are unpublished data, I would ask you to include Richard as a coauthor if you intend to publish anything based on this.

Re: [arts-users] Temperature Retrievals of Oxygen emission lines with Zeeman effect and line mixing
Dear Witali, You can use my calculations for line mixing. They are still not published but available online in the arts-cat-data. They have the disadvantage that they are not published but the advantage that they are self-consistent. You can download this data at https://www.radiativetransfer.org/tools/, under the Arts Catalog Data header. The format is simply x0 x1 x2 x3 from table 2.5 of the theory guide at the correct positions by what the xml-tags say. Note that the paper you found has been updated several times. Two updates are at these dois: http://dx.doi.org/10.1016/j.jqsrt.2013.02.019 and https://doi.org/10.1016/j.jqsrt.2019.106798 Note especially that these correct their values in the first paper because they found some theoretical errors. Also note that my implementation in Arts today differs from the one written in these papers because there are some weird typos in there.

[arts-users] Temperature Retrievals of Oxygen emission lines with Zeeman effect and line mixing
Dear ARTS Team I am currently using the Zeeman module to retrieve stratospheric temperature profiles from oxygen emission lines from fine structure transitions at 52.542 and 53.067 GHz. I correct for the tropospheric influence using a simple tropospheric correction. However, I intend to improve the inversion algorithm by including line-mixing calculations instead. First, I am having trouble figuring out how to get line-mixing data. I found "Makarov, Tretyakov, and Rosenkranz, 2011" as a standard reference for line-mixing data in this frequency range. However, it seems to me that only the emission complex at 60 GHz is covered there. Is there any line mixing data for the emission lines at 52.542 and 53.067 GHz? Also, I would need some guidance on the implementation of the line mixing module. I guess the data set should be in a certain format, which I did not find in the ARTS manual or documentation (maybe I missed something?). With kind regards Witali Krochin
