Binary_SED_Fitting v3.4.0

Fitting stellar SEDs for single and multi-component systems.

Documentation at jikrant3.github.io/Binary_SED_Fitting

Requirements

• python >= 3.12.2

• astropy >= 6.0.1

• matplotlib >= 3.8.4

• numpy >= 1.26.4

• pandas >= 2.2.1

• scipy >= 1.13.0

• xarray >= 2024.3.0

  • Installation: python3 -m pip install xarray
  • Install the dependencies for handling I/O: python3 -m pip install "xarray[io]"

Installation

• Add the binary_sed_fitting.py to your working directory.

  • ⚠️ Edit the DIR_MODELS in the binary_sed_fitting.py file according to where your model files are located

• Download the required models from Google Drive. More information about how to make these model files is given in models_and_tools.

  • Currently supported spectral models:

    • kurucz_synthetic_photometry.nc (Kurucz 2003IAUS..210P.A20C)

    • koester_synthetic_photometry.nc (Koester 2010MmSAI..81..921K)

    • kurucz_uvblue_synthetic_photometry.nc (Hybrid Kurucz_UVBLUE 2005ApJ...626..411R)

  • Isochrones: master_isochrone.csv (Parsec isochrones)

  • WD cooling curves: master_Bergeron_WD.csv (Bergeron models)

Caution

⚠️ The software is under active development.

The code has been designed for 3 component SEDs. However, only double component fitting is thoroughly tested.

Reference :

This code is developed by Vikrant V. Jadhav (Universität Bonn) and Sindhu Pandey (IIA).
