The new user manual dedicated for the Aladin Beta release - in French, and soon in English...

Description Aladin is an interactive software sky atlas allowing the user to visualize digitized astronomical images, superimpose entries from astronomical catalogues or databases, and interactively access related data and information from the Simbad database, the VizieR service and other archives for all known sources in the field (see available data).
Created in 1999, Aladin has become a widely-used VO portal capable of addressing challenges such as locating data of interest, accessing and exploring distributed datasets, visualizing multi-wavelength data. Compliance with existing or emerging VO standards, interconnection with other visualisation or analysis tools, ability to easily compare heterogeneous data are key topics allowing Aladin to be a powerful data exploration and integration tool as well as a science enabler.
The Aladin sky atlas is available in three modes: a Java Standalone application, a Java applet interface and a simple previewer.

Portions of the code (FoV advanced integration, Fits cubes, Xmatcher by ellipses, Plastic integration)) have been developed in the framework of EuroVO VOTech project (2005-2008).
Portions of the code (contours, filters, metadataTree) have been developed in the framework of the Astrophysical Virtual Observatory (AVO), an EC RTD project 2002-2004
The RGB feature has been developed in the framework of the IDHA project (ACI GRID of the French Ministere de la Recherche).
