line list completion in TS format #24

Open ainun-azhari opened 1 week ago

ainun-azhari commented 1 week ago

I am fitting a Th line at 4019.130 Å, where there are multiple blends from atomic and molecular lines. I use the TS line list from VALD for 3800-4300Å, but I need to add some more lines to the line list. I got the line data from the literature, but they only give the wavelength, log gf, and excitation potential. I read TS documentation that some other information is needed (gup, etc.), and I could not find this on VALD or Kurucz's online line list (the lines I need are not available there for some reason). As I need these lines to be included in the fitting, I wonder if I could use only wavelength, log gf, and excitation potential for these lines to complete the line list. I would appreciate any advice!

If you only know wavelength, gf, and Ei, you may enter 1.0 for damp (will use Unsöld recipe), 1.0 for gup (or use glow instead), 0 for gamma_rad, 0 for gamma_stark, 'X' and 'X' for levels. Line broadening will not be computed accurately, but that allows you to include the lines

thank you! as I include those lines only to take blends into account, how much would the broadening affect the abundance of the line I'm fitting (in this case, Th)?
