Installation of recent graphic drivers resolves performance problems. On Linux one can verify proper hardware acceleration using the glxinfo command. A 32 bit linux machine (i86 architectures only) or MacOSX or Windows 32 bits.On Windows: download the zip file, uncompress it and double click on stellarium.exe.dmg file, open it and run the VirGO executable. For example, issue the following commands on a terminal:
VirGO.sh in a console from the new directory. On Linux: download the package, uncompress it and run.If a previous installation of Stellarium exists, one may need to delete the $HOME/.stellarium directory to restore the default configuration.VirGO-1.4.5-macosx-intel-snowLeopard.dmg (60mb) VirGO-1.4.5-macosx-universal-leopard.dmg (54mb) It is possible to add some extra star catalogs to allow seeing more than the default 2.3 million stars (up to 210 millions) by downloading them from the Configuration window within the program. The package contains a binary version of Stellarium, the VirGO plug-in for ESO archive access and some extra star catalogs and landscapes. VirGO-1.4.5 (Jan 15th 2010) is distributed as a binary compiled for linux-i386 and windows and MacOSX. These screenshots illustrate some of the main features of VirGO such as footprints, DSS background, images previews or browsing through large number of data sets.
Data interfaces are based on Virtual Observatory standards enabling access to images and spectra hosted by other data centers and to exchange data with other VO applications through the PLASTIC messaging system.Ī large fraction of ESO's non proprietary science products are already accessible through VirGO and more are to come:ĭata Availability Status Page Screenshots
It superimposes DSS background images and allows to view the sky in a real life mode as seen from the main ESO sites. It reads FITS images and catalogues in VOTable format.
Its main feature is to perform real-time access and graphical display of a large number of observations by showing instrumental footprints and image previews, and to allow their selection and filtering for subsequent retrieval. VirGO gives astronomers the possibility to easily discover and select data from millions of observations in a new visual and intuitive way. It is a plug-in for the popular open source software Stellarium with added capabilities for browsing professional astronomical data. VirGO is the next generation Visual Browser for the ESO Science Archive Facility developed by the VO Systems Department.
