Thank you for the quick reply and comments on the updated papers.
We will definitely add Mr. Larsson to the list of co-authors when the research using this dataset is published. Unfortunately, I am already having problems reading the dataset. I have downloaded the file "O2-66.xml" from https://arts.mi.uni-hamburg.de/svn/rt/arts-cat-data/trunk/lines/, but I cannot read the file with any reading function that are known to me. For example, the following line: "ReadXML(abs_lines, "O2-66.xml")" Generates the following error message: "Species "" is not a valid species." I've tried several other read functions, but I have a feeling I'm missing something.

Best wishes Stefan Am 12.09.2022 um 14:09 schrieb Richard Larsson <ric.lars...@gmail.com>: 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. With hope, --Richard Den mån 12 sep. 2022 kl 13:30 skrev <witali.kroc...@unibe.ch<mailto:witali.kroc...@unibe.ch>>: 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
