fit-BEL

End-to-end code to estimate AGN properties from a single spectrum by fitting the continuum and a Broad Emission Line (BEL)

Usage

Clone the repository on your local machine:

git clone https://github.com/Alexperiments/fit-BEL.git

Enter the newly created folder:

cd fit-BEL

Create a virtual environment

python -m venv my_env

Activate the virtual environment for Unix OS:

source my_env/bin/activate

If you are running Windows use this instead:

.\my_venv\Scripts\activate.ps1

Install required dependencies into the virtual environment:

pip install -r requirements.txt

Run fit-BEL as:

python fit-BEL.py examples/sample.fits -z 3.1 -e 2.1

Run:

python fit-BEL.py -h

to get more information about the optional arguments

Development

Tasks

• Adapt the original code to a single script:
  • Basic spectrum plot
  • Add interval selection procedure
  • Add continuum fit procedure
  • Add mask selection procedure
  • Add fit selection procedure
  • Add parameters estimation
  • Refactor the code to allow models modularity
  • Add error estimate procedure

Bugs

• Fix the zoom reset
• Fix the masks re-draw
• Fix FWHM calculation

New features

• Add different file formats in addition to .fits and .txt
• Add different fit components in addition to gaussian ones.
