Come analyze HEASARC, IRSA, and MAST data in the cloud! The Fornax Initiative is now welcoming all interested beta users.

Multi-Mission 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. (HEASoft/FTOOLS, a general library of FITS file utility programs and mission-specific data analysis tools can be found on our Software page.)

  • 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 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
