Web-Based Tools

These Web-based tools are designed to assistscientists in their proposal and general data analysis efforts. TheHEASARC provides these tools as a service to the scientific community.(HEASoft/FTOOLS, a generallibrary ofFITS file utility programs andmission-specific data analysis tools can be found on ourSoftware 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 the neutral hydrogen column density by skycoordinates
• Time/Date Converter (xTime)– Convert between Julian date formats and standard date formatssuch as YYYY-MM-DD
• Universal Atomic Database – Find atomic physics quantities needed for astrophysical research
• X-Ray Background– Calculate average X-ray background count rates from the ROSATAll-Sky Survey diffuse background maps
• X-Ray,Gamma-Ray, and EUV Source Finder – Is your favorite object ahigh-energy source?

Multi-Mission Tools

• SciServer– A science platform for data analysis over the Internet
• RPS– Remote Proposal System
• Date/Time Converter (xTime)– Convert Fermi, RXTE, Suzaku, Swift, and XMM-Newton times toother 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
