Piece by piece:

The Outreach version is a simplified version of Aladin Desktop dedicated for undergraduate students. The choice of the images and catalogues has been reduced in order to offer a selection of the most important data without embarrassing the user with too many alternatives or with too sophisticated data. Also the choice of functions activated directly with buttons and switches has been reduced to ease learning curve required by the sofware. This developement has been done in the framework of the EuroVO AIDA project (2008-2010).

The beta version incorporates new features in test phase for the next official Aladin version. The stability of these features is not totally guaranteed. The beta version is regularly updated following the progress of the Aladin developement team.

New features and performance improvements:

  • Fisheye projection support (ARC) => planetarium usage
  • Fullscreen mode improvements (global menu)
  • MOC script support (cmoc command)
  • MultiCCD image support
  • Tags improvements
  • Probability sky map MOC extraction
  • Planetary HiPS (longitude inversion)
  • Hipsgen improvements: HiPS color multithread code, local MIRROR, APPEND, MAP
  • File dialog window multi-selections

Major fixed bugs:
