Hi Witali, The line mixing does not matter yet.
OK, not 0/0 but you simply are not having any quantum numbers at all (these are the the missing numbers) The nan numbers will matter later. You will see another error if you fix the first problem. I would suggest you just keep lines with v1=0 anyways, since you won't have any effect from the v1=1 band. The problem with the missing quantum numbers at the end of the catalog is there because you are reading a HITRAN .par file. We deprecated quantum number reading from the .par files because they were not reliable. To still read raw HITRAN, you can download it again from their https://hitran.org/lbl/ webpage, selecting the species you want to use (presumably only O2-66). You then need to modify the parameter options so that the first entry is the full .par, the second entry is qns', and the last entry is qns''. I attach a picture of how the webpage selection looks to me. This way, all species in HITRAN will have all their quantum numbers read properly. You can load these into ARTS using ReadHITRAN method again, but setting hitran_type="Online". This will load all the quantum numbers into ARTS and also set the Zeeman effect from pure calculations as far as I remember. We maintain a curated version of HITRAN in the arts-xml-data in case you do not wish to do this. I was hoping to add line mixing to it down the line but I couldn't find the mixing in HITRAN online last I checked. With hope, //Richard Ps. picture of HITRAN selection box: [image: Screenshot from 2020-11-26 12-14-24.png] Den ons 25 nov. 2020 kl 17:58 skrev <witali.kroc...@iap.unibe.ch>: > Dear Mr. Eriksson > > > Thank you for the answer. > > Since i had my script in qpack, I just generated abs_lines in ARTS 2.4 in > a short way to demonstrate my setup. > > > The code was > > > Arts2{ > abs_speciesSet(species=["O2-Z-66-53.0469e9-53.0869e9","O2-66"]) > VectorCreate(gs) > ArrayOfQuantumIdentifierCreate(qid) > ReadXML(gs, "/arts-xml-data-2.4.0/spectroscopy/zeeman/O2-66.g.xml") > ReadXML(qid, "/arts-xml-data-2.4.0/spectroscopy/zeeman/O2-66.qid.xml") > ReadHITRAN(abs_lines,"HITRAN2012.par") > abs_linesSetZeemanCoefficients(abs_lines, qid, gs) > WriteXML( "ascii", abs_lines, abs_lines.xml") > > It seems to have some 'nan' entries.
