Version 2.1 January 2005 | Improvements were made to the graphing procedure. |
Version 2.0 May 2003 | Improvements were made to the values for the medium-Z soft X-ray edges addressing convergence issues of earlier work. Additional features that were added include data output: for compounds, for linear attenuation coefficients, and for user-defined densities. An additional data output format was added to address the Section 508 accessibility requirements. |
