the GoalProvide a way for astronomers to easily find complementary data in multiple telescope archives.
the Motivation• Astronomers who work at other wavelengths
have requested VLA data to complement their own data sets.
• Increase accessibility of archival data, especially pre-processed data.

Upshot for Archive Access
• The application I’m developing may demonstrate a nice user interface to archival data.
• Highlights the relevance of multi-archive & multi-wavelength data access.
• Demonstrates the usefulness of VO tools and standards.

Accessing Multiple Archives
• A standard protocol for obtaining archival metadata: VO Simple Cone Search (SCS).
• SCS is intended to provide catalog data, but some services distribute archival metadata instead.
• For lack of a better alternative, use SCS.

The Application
Crossmatch consists of 3 parts:1. Static web content (HTML & JavaScript);
provides a query page for data searches and a framework for VOView.
2. VOView: a client-side VO app that provides a web browser user interface to VO Table data.
3. A proxy service; allows the user to acquire data from other domains

VOView
• Designed as an efficient interface to VO Tables with 1000 to 100,000 rows.
• Uses XSLT to quickly process data• Provides:
Pagination, Sorting, Filtering, Dynamic column re-ordering, showing/hiding columns, easily export data (XML, ASCII, …), Display column units, datatypes, & descriptions

To-do List
• Collapse partially redundant rows
• Link table rows directly to archive data
• Increase interactivity between display windows (sorting, filtering, …?)
