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
Coordinate Converter - CoCo: Object location and coordinate
converter
Date Converter - Convert between Julian date formats and more
recognizable date formats
Energy Converter - Energy/frequency/wavelength converter
nH Column Density - Determine neutral Hydrogen column density by target coordinates
X-Ray Background - Calculate average X-ray background count
rates from the ROSAT All-Sky Survey diffuse background maps
TIPTOPbase - An on-line database of atomic data (energy levels,
f-values and photoionisation cross sections) compiled by the
Opacity Project This link now redirected to Vizier
X-Ray, Gamma-Ray, and EUV Source Finder: Is my favorite object a high-energy source?
Bibliography - Query NED, SIMBAD, and ADS for bibliographic
references
FITS file verifier - Run fverify on any of your own FITS files
Multi-Mission Tools
