Echelle

Echelle is a Python package for plotting and interacting with echelle diagrams. In an echelle diagram, the amplitude spectrum of a star is stacked in equal slices of delta nu, the large separation.

Installation

pip install echelle or download the git repository and python setup.py install

Usage

For a dynamic interface:

from echelle import interact_echelle
interact_echelle(frequency, power, dnu_min, dnu_max)

If you're using echelle in a Jupyter notebook, I suggest calling %matplotlib notebook first.

To plot a non-interactive echelle diagram,

from echelle import plot_echelle
plot_echelle(frequency, power, dnu)

See the example.ipynb for common usage!
