Code papers (please cite these if you use Korg):

• Korg: A Modern 1D LTE Spectral Synthesis Package
• Korg: fitting, model atmosphere interpolation, and Brackett lines

Tutorials:

• Korg basics
• Korg basics in python
• other tutorial notebooks

Example

using Korg, PyPlot
lines = Korg.get_GALAH_DR3_linelist()
A_X = format_A_X(-1.1, Dict("C"=>-0.5))
atm = interpolate_marcs(5000.0, 4.32, A_X)
sol = synthesize(atm, lines, A_X, 5850, 5900);

figure(figsize=(12, 4))
plot(sol.wavelengths, sol.flux, "k-")
xlabel(L"$\lambda$ [Å]")
ylabel(L"$F_\lambda/R_\mathrm{star}^2$ [erg s$^{-1}$ cm$^{-5}$]");

You can also call Korg from python

See the documentation for setup instructions.
