ipyaladin

A bridge between Jupyter and Aladin Lite, enabling interactive sky visualization in IPython notebooks. With a couple of lines, you can display Aladin Lite, center it on the target of your choice, and overlay an Astropy table:

• ipyaladin
  • Examples
  • Installation
  • New features corner
  • Development installation

Examples

Some example notebooks can be found in the examples directory.

. You can also try it directly in mybinder, without installing anything.

Installation

To install use pip:

pip install ipyaladin

Then, make sure to enable widgetsnbextension:

jupyter nbextension enable --py widgetsnbextension

Finally, enable ipyaladin:

jupyter nbextension enable --py --sys-prefix ipyaladin

And you are ready to use ipyaladin inside your notebooks! Additionny, for a jupyterlab usage you will need to:

jupyter labextension develop ipyaladin --overwrite

There is also a conda package that can be installed with:

conda install -c bmatthieu3 ipyaladin==0.2.5

Development installation

First, make sure you have installed jupyter on your python environnement: pip install jupyter. For a development installation Node.js and Yarn version 1 are also required,

git clone https://github.com/cds-astro/ipyaladin.git
cd ipyaladin
npm install yarn
cd js
npm install
cd ..
pip install -e .

For Jupyter Notebook, do

jupyter nbextension install --py --symlink --overwrite --sys-prefix ipyaladin
jupyter nbextension enable --py --sys-prefix ipyaladin

For JupyterLab, you will need to run this command too:

jupyter labextension develop --overwrite ipyaladin

Then you need to rebuild the JS when you make a code change:

cd js
yarn run build

You then need to refresh the JupyterLab page when your javascript changes.
