ipyaladin example

With a couple of lines, you can display Aladin Lite, center it on the target of your choice, and overlay an Astropy table:

ipyaladin example


Some example notebooks can be found in the examples directory.

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


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

There is also an experimental conda package that can be installed with:

$  conda install -c tboch ipyaladin 

For a development installation (requires npm) you can either do:

$ git clone
$ cd ipyaladin
$ pip install -e .
$ jupyter nbextension install --py --symlink --sys-prefix ipyaladin
$ jupyter nbextension enable --py --sys-prefix ipyaladin

or directly use the script:

$ git clone
$ cd ipyaladin
$ ./

Note: Sometimes the module installation crash because of a conflict with an older occurence of itself, if so to solve this problem go to: ~/anaconda3/share/jupyter/nbextensions Then suppress the ipyaladin corrupted file.

Running in JupyterLab (experimental)

To enable ipyaladin in JupyterLab:

$ git clone
$ cd ipyaladin/js
$ jupyter labextension install
