Aug 15, 2002 Support to write small value which can't describe by %6.4f . May 28, 2002 Improvement of reading experimental data.2003 5/6 Support of charge exchange. When radiobutton of charge exchange is selected, the parameter of charge exchange will become effective.2003 5/12 Add. splitter between composition and thickness panel.2003 5/13 Display of atomic density for each target, when mouse cursor stop at target cell.2003 5/16 Support of summation of atomic density on the depth profile window (E15atoms/cm2).2003 5/19 Small bug fix of reading multiple files on Graph window.2003 5/19 Small bug fix. The correspondence between target structure and depth profile which was used in simulation are improved. The correspondence was really bad when target structure has gradient value. Now, program use average composition to convert the thickness(A) to a thickness(atoms/cm2).2003 5/19 Modification of minor tick count on Graph windows. (3->4)2003 5/22 Modification of charge exchage. The ion fraction will be calculated from charge exchange parameter at surface region as same as old version. For deeper region, the value depends on energy acording to Marion&Young or Brett. This consideration was made for thick samples.2003 7/16 Bug fix. Offset Channel was not displayed when initial file was reloaded.2003 9/12 Modification of procedure of experimental file name. Old : RelativePath(filename) New : RelativePath(ExpandFileName(filename))2003 9/12 Modification of scale tool. Old : The setting of scale parameter was not reflected when mei file are opened again. New : It was improved.2003 9/12 Improvement of behavior when isotope element was entered.
