Web-based Tools

These Web-based tools are designed to assist scientists in their proposal and general data analysis efforts. The HEASARC provides these tools as a service to the scientific community. [FTOOLS, a general FITS file utility programs and mission-specific data analysis tools can be found on the Software page].

General Tools

• Bibliography – Bibliographic references to HEASARC services and missions
• Coordinate Converter – CoCo: Object location and coordinate converter
• Energy Converter – Energy/frequency/wavelength converter
• FITS File Verifier – Run fverify on any of your own FITS files
• nH Column Density – Determine neutral Hydrogen column density by target coordinates
• Date/Time Converter (xTime) – Convert between Julian date formats and standard date formats such as YYYY-MM-DD
• X-Ray Background – Calculate average X-ray background count rates from the ROSAT All-Sky Survey diffuse background maps
• X-Ray, Gamma-Ray, and EUV Source Finder – Is my favorite object a high-energy source?

Multi-Mission Tools

• Hera – Astronomical data analysis over the Internet
• RPS – Remote Proposal System
• Date/Time Converter (xTime) – Convert Fermi, RXTE, Suzaku, Swift, and XMM-Newton times to other time systems and formats, and vice versa
• SkyView – The Internet's Virtual Telescope
• Timeline Tool – Swift, RXTE and HETE-2 observation (as-flown) timelines
• Viewing – Determine possible viewing times for missions and objects
• WebPIMMS – Determine source flux or count rates
• WebSpec – Simulate spectral data for missions/instruments

Cosmic Microwave Background Analysis Tools
