Description Fellype 2018-05-03 19:06:01 UTC
Dear Kalzium maintainers,
Taking a look at the emission spectra of some elements in Kalzium I have seen that there are a lot of line emissions missing there.
If you want, I can provide you more lines for some elements, focusing on those that are most important/useful in emission spectroscopy (before you ask, I'm a specialist in plasma spectroscopy).
If you want do get a list of line emissions of elements by yourself, I would recommend to you to use the NIST database available at https://physics.nist.gov/PhysRefData/ASD/lines_form.html

Best regards.

There is a data file Kalzium uses at https://cgit.kde.org/kalzium.git/tree/libscience/data/spectra.xml

I am not sure if this Kalzium data file is generated from some database maintained elsewhere, and maybe that database already provides extra spectral information. In this case, we would need to find the original database, and update Kalzium's copy.

Otherwise, maybe you could provide an updated file (or a .diff) with the extra information you would feel is important, and Kalzium developers could review them. I haven't checked where the "e<Number>" mapping to actual elements is made, or if this number is the actual element number.

Dear Christoph,

I'll work on an update for the spectra.xml file in next weeks. I'll start with the elements that are most used in the literature: H, He, Ar, O, C and N, and, in the future, update the remaining elements.

Best regards

Thank you for reporting this issue in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the issue with a recent software version?

If you can reproduce the issue, please change the status to "REPORTED" when replying. Thank you!

Dear Justin,

The issue is still present in Kalzium 21.12.3 (the version I'm running right now). I guess that no one tried to solve it in newer versions.
I proposed myself to do the job a long time ago (see comment #2). In fact, I started working on that. However, I never had time to finish the job and I forgot to send what I had done. At the moment I don't have access to the computer I used to work on that (I'll be back in Feb 2023). So, if someone else want to fix the issue I'll be really happy. Otherwise, please, remember me (in, let's say, 4 months) to send to the project at least what I already did.

Best regards
