What is aladin
aladin is:
Aladin is an interactive software sky atlas allowing the user to
visualise digitised astronomical images, to superimpose entries from
astronomical catalogues or databases, and to interactively access
related data and information from the Simbad database, the VizieR
service and other archives for all known sources in the field.
Created in 1999 by the Centre de Données astronomiques de Strasbourg
(CDS), Aladin has become a widely-used tool of the Virtual
Observatory (VO) framework capable of addressing challenges such as
locating data of interest, accessing and exploring distributed
datasets, and visualising multi-wavelength data. Compliance with
existing or emerging VO standards, interconnection with other
visualisation or analysis tools, and the ability to easily compare
heterogeneous data are the key topics which allow Aladin to be a
powerful data exploration and integration tool.
