AXAF Project Science: EIPS Catalog

There is a programming error in the calculations of "line purity". The error affects any targets with more than one line; the more lines the worse the error. The plots and tables for "line purity" from the online catalog should not be used until corrections have been made.

• The tables (ASCII) and plots (GIF) of spectra are arranged in sets of voltages that are multiples of the K or L edge energies.
• Plots of unfiltered spectra are available where the spectra from all voltages are overlapped (plot1) or appear on separate plots (plot2). The plots of filtered spectra are overlapped.
• Line purity results give the line fraction (number of counts in the line to that in the 0.1 - 10.0 keV band) and the detected photon energy dispersion.
