OSLO Standard Analysis

All graphic windows are resizable, zoomable and updatable. A recall parameters dialog box (to set field point(s), wavelength, scales...) and direct on-line help are easily accessible. Several graphical analysis routines formerly in the built-in library have now been supplied in CCL, making it easy to customize output for special requirements.
