HEASARC Web Utilities: General Tools

General 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].

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
Time/Date Converter (xTime) – Convert between Julian date formats and standard date formats such 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 ROSAT All-Sky Survey diffuse background maps
X-Ray, Gamma-Ray, and EUV Source Finder – Is my favorite object a high-energy source?

Sesame (VizieR) name resolver support added to HEASARC tools (28 Oct 2015)
Support for resolving the names of astronomical objects according to VizieR using the Sesame name resolver service has been added to the HEASARC's Coordinate Converter, Viewing, nH, X-Ray Background, and the High Energy Source Finder tools, as well as ARK/RPS, Browse, and Argus. This feature is particularly useful in resolving Sloan Digital Sky Survey (SDSS) object names, for example.
