We describe a new plug-in for the Aladin Desktop software to analyze 3D
sky maps of gravitational-wave sources. Aladin is the most used VO (Virtual Observatory) software for digitized astronomical images and gravitational-wave sky maps visualizer.
Extending its functionalities is challenging and helps in developing astronomical
technical standards, as IVOA (International Virtual Observatory Alliance) promotes.
Here, a Python algorithm has been developed to allow any Aladin user to immediately receive information about the probability distributions of having a gravitational-wave source along a line of sight in any given position of the sky map, just by clicking on that pixel.
