Dear Claudia, There is no news. It worked quite well recently in ARTS 2.5.X when last I updated our redistributed catalog (at the arts-cat-data subversion server; though this is not pure Hitran as we have some line mixing and line shapes we select manually included). I just confirmed that this still works by manually downloading some data.
The box titled: Available Parameters contains all parameters. It is a scroll box. It is available after you select to create a new format, so you should see it. You have to scroll down a bit to see the three fields I mentioned last year, but they are still there. With hope, //Richard Den mån 16 jan. 2023 kl 17:01 skrev Claudia Emde <claudia.e...@lmu.de>: > Dear ARTS community, > > I have exactly the same problem that Pengwang has reported.
