8 months ago Hi Sagi,
It appears that Turbospectrum is not running correctly on your machine. Have you downloaded the most recent version of Turbospectrum and checked that it runs outside of TSFitPy?
Cheers, Jeff
Dear Jeffrey.
My name is Sagi Ben-Ami, and I am a faculty member at the Weizmann institute of Science in Israel.
My main focus is on developing astronomical instruments, but at the moment I am also interested in stellar astrophysics, with a focus on Ba stars.
I have downloaded your TSFitPy package, in order to use it to estimate Ba abundances in several spectra, and am trying to run it following the example on github. However, my output, reproduced below, indicates my run is not fitting any line.
Can I kindly ask you to take a look and see if you can identify an error or mistake in the way I run the example ?
(I did notice that the actual output directory name is Jan-04-2024-10-56-22_0.7717720470148655_LTE_Fe_1D and not Jan-04-2024-10-56-22_0.7717720470148655 as in the temp_directory generated, but I assume it is not the issue).
Thanks in advance - the package you are authoring is of great help for the work I am trying to promote, and I will of course give proper credit in any possible future publication.
All the best - and happy new year,
Sagi.

IMPORTANT UPDATE: Update 24.05.2023. Currently the assumption is that the third column in the observed spectra is sigma i.e. the error in the observed spectra (sqrt(variance)). If this is not the case, please change the spectra.If none is given, the error will be assumed to be 0.01. This error is taken into account in chisqr calculation
