Disclaimer

This program is in its beginning stages. It is possible to fit and extract 1D spectra from 2D spectrograms.
A spectral calibration is under development.
Everything has been tested in a native python environment. Currently we have no experience using conda environments.

Before you start

python -m pip install --upgrade pip
pip install --upgrade setuptools
pip install -r requirements.txt

Start QtYeti

• Navigate to the directory where QtYETI has been extracted to
• Start the program via

python ./QtYeti.py

Features

In the Calibration Tab you can find a geometric calibrator that has been used to sucessfully predict ThAr lines in our manuscript.
