Nancy S. Brickhouse

• Dec 13, 2002 Release of ATOMDB Version 1.3.0
  
  • Highlights Fe K-alpha calculations
  • Fixes Ni XXVI extrapolation at high temperatures
  
  

• (AstroAtom) Demonstration
  
  • Web forum to facilitate communication between atomic physicists and astrophysicists
  • Will accept postings from registered users of new papers, conference announcements, or questions
  • Will facilitate the search for atomic data by astrophysicists, will help atomic physicists to determine what calculations might be useful
  
  
• (WebGUIDE) Demonstration
  • Line identification tool
  • Commands also available in sherpa, using import(``guide'')
  identify, given wavelength, [range width , minimum emissivity]
  describe, given element, ion, lower level, upper level
  strong, given temperature, [minimum emissivity, min and max wavelength]
