neloura 0.1.9

A local web viewer and analysis app for astronomical FITS images.

Neloura

Neloura is a local web application for opening, visualizing, and analyzing astronomical FITS images.

This package can be run from the command line:

neloura serve
neloura open path/to/image.fits

It can also be used inside Jupyter:

import neloura

neloura.open_fits("path/to/image.fits")

In Jupyter, open_fits() starts a local Neloura server and displays the full app in an iframe below the notebook cell. Outside Jupyter, it opens the app in a browser tab.

On JupyterHub-style remote notebook servers, Neloura automatically uses the notebook server proxy when JUPYTERHUB_SERVICE_PREFIX is available, so the same calls work from a browser connected to a remote kernel:

import neloura

neloura.open_app()
neloura.open_fits("path/on/server/image.fits")

Development Install

From the repository root:

python -m pip install -e ".[notebook]"
neloura serve

On shared notebook servers where the system Python is not writable, install into the user environment:

python -m pip install --user -U neloura

Build

python -m pip install -U build twine
python -m build
twine check dist/*
