VO-Software

In this section, scientists can find available VO-compatible applications for their immediate use to do science. The level of maturity of the applications depends on a high degree on the level of maturity of the corresponding IVOA protocols and standards, and care must be taken when using them for publications.
As a consequence of the flexibility of the standards, several of the applications might overlap in functionality.

Please make use of the applications and send us any comment by accessing our helpdesk system.

Historical Software

AVO Prototype A tool that allows Image manipulation of resources from within the VO. Other utilities can be accessed from the tool. It was used at the latest AVO Demonstration in 2005. This tool was based on an earlier version of Aladin (see above)
