## The HEASARC On-line Services

- Tom McGlynn

## Summary

- On-line services overview
- New capabilities
- Browse and the archive
- Browse demo

## Web Services: Information tools

- nH:  Galactic hydrogen column
- X-ray background: ‘Diffuse’ X-ray background
- Source finder: Is this a known HEA source?
- Timeline: What did satellites actually do?

## Web Services: Proposal Tools

- RPS: Multi-mission proposal software
- INTEGRAL, RXTE, Suzaku, XMM
- Viewing: Who can see where when (Demo)
- Chandra, HST, Suzaku, RXTE, Swift, XMM
- WebSpec: Simulate observed spectra
- ASCA, BeppoSAX,  Chandra, Con-X, ROSAT, RXTE, Sazuku, Swift, XMM
- WebPIMMS: Convert counts
- ASCA, BeppoSAX, CGRO, Chandra, Con-X, Einstein, INTEGRAL, ROSAT, RXTE, Sazuku, Swift, XEUS, XMM

## Web Services: Utilities

- Target/position converters: Find positions of named targets, convert coordinates.
- Data/Time converter: Convert among time representations and systems. (Demo)
- Energy converters: Unit conversion
- FITS validator: Run FVerify on uploaded data

## Web Services: Miscellaneous

- AKBAR: Allow users to update tables (used within RPS and for Swift GRB updates)
- Argus: Follow observations through proposal/observation cycle.
- XTE Weather Map: What is active in the sky? (Demo)
- Software download utilities: Find the software tools for your analysis needs.
- SkyMorph: Look for moving targets in data.
- Hera*, SkyView* and VO services discussed later.

## What’s new

- AKBAR
- Argus revised
- Now a specialized interface to Browse
- Coordinate list converter
- Combined date and time converters
- More missions and such in many tools
- Revamped RPS
- GRB name resolver (in development)

## Browse

- Primary interface to HEASARC catalogs and archive.
- Multiple interfaces with varying complexity and power.

## What’s new in Browse

- Swift tables and data
- Tabbed results (in development, demo)
- Keyword search interface (demo)
- Simple but powerful query interface
- Enhanced text interface
- Retains most capabilities of default HTML table display but is much faster.
- Filtering of data products
- Select only files matching template
- Special Swift interface
- Improved internal plotting
- Links to Hera (demo)

## Browse

- (and anything else you would like to see)
- Demos

## Tabbed Output

- Breaks down Browse output into manageable chunks.
- Different functions available on different tabs
- Missions and tables conveniently organized
- Shopping cart paradigm for data product retrieval
- Users select products associated with each table, then go to retrieval form.
- Still under development, suggestions very welcome!

## Keyword Search Interface

- Google-esque style search:  Users enter text describing what they want and Browse tries to find it.
- Distinguishes times, positions, formats, table selection keywords automatically.
- Supports search by position, time or any parameter.
- Allows selection of tables by name, mission, regime, ...
- Tables selected by matching keywords.
- Uses JavaScript and AJAX to give users feedback as they are entering information.

## Possible next steps

- User defined samples
- Correlations with large external catalogs (e.g., SDSS, Galex)
- Probably using VO protocols
- Automated notifications for new observations
- VO access to HEASARC images and spectra
- ...
