View a welcome and introduction to the VAO Science Tools from director Robert Hanisch:
VO Tools and Applications from Other VO Projects and the Research Community
Below is just a selective sample of the VO tools and services that have been developed by various Virtual Observatory projects around the world. For a more complete listing, see this evolving list at the IVOA Applications Working Group page. Prototypes produced by the predecessor to the VAO are still available at http://www.us-vo.org
- Monitor real-time alerts of transient events: Skyalert
- Manipulate tabular data graphically: TOPCAT
-
Query & cross-match VO databases: seleste
- Find & overlay images at different wavelengths: Aladin
- Make mosaics from 2MASS, DPOSS, or SDSS: Montage
- Plot results from VO queries: VOPlot
- Reduce, analyze, & display astronomical data within the IRAF environment, with enhanced VO capabilities IRAF v. 2.16
- Perform simple & sophisticated statistical routines on large datasets: VOStat
