Documentation for neddy is hosted by Read the Docs (development version and master version). The code lives on github. Please report any issues you find here.

Features

• A command-line suite to query NED for a given source name or via a sky-location conesearch.
• The ability to send multiple name or conesearch queries with a single command.
• Integrate neddy into your own python scripts to build your own workflows.

Installation

The best way to install or upgrade neddy is to use conda to install the package in its own isolated environment, as shown here:

conda create -n neddy python=3.9 neddy -c conda-forge
conda activate neddy

If you have previously installed neddy, a warning will be issued stating that a conda environment already exists; select 'y' when asked to remove the existing environment.

To check installation was successful run neddy -v. This should return the version number of the install.

Initialisation

Before using neddy you need to use the init command to generate a user settings file. Running the following creates a yaml settings file in your home folder under ~/.config/neddy/neddy.yaml:

neddy init

The file is initially populated with neddy's default settings which can be adjusted to your preference.

If at any point the user settings file becomes corrupted or you just want to start afresh, simply trash the neddy.yaml file and rerun neddy init.
