[Artist's Concept of AXAF-I] 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.
