Getting Started

Dependencies

  • Fortran 90

  • Python 3.9 & pip

Installation

  1. Go to the folder of your choice, then clone the git directory with the command :

git clone https://gitlab.com/LeiRoF/fitting-spectra

  1. Move to the project folder

cd fitting-spectra/

  1. Install the dependencies of the Python program allowing the display of the results in the form of a graph

pip install -r ./requirements.txt

  1. Using GFortran, compile the fortran files

gfortran -o fit_spectra ./fit_spectra.f90
gfortran -o fit_omega ./fit_omega.f90

Usage

This project contains 2 independent programs:

  • Fit Spectra aims to determine a Lorentzian function from a set of given points via a file in ./data/

  • Fit Omega then allows you to do a linear regression, which in the context of this project allows you to determine the fundamental rotational energy of the gas.

You can edit the fit_spectra.f90 and fit_omega.f90 files to modify the file in question. Once edited, perform step 3 of the installation (compiling the Fortran files) again

Launch Fit Spectra

./fit_spectra

Run Fit Omega

. code-block:

./fit_omega

Note

If an error appears at the end of the program execution and no window appears, you can open it manually by using your browser to open the file plot_spectra.hmtl or plot_omega.html
