1D Fit

Load the 'CaAlGlass.1r' file by [File/Open], by dragging the file to dmfit or by double clicking if configured.

[Menu/Decomposition/Load Fit]

wait for the computation do be done (it takes time...)

The fit consist in 9 lines :
  • 3 CzSimple lines for the central transitions of AlIV, AlV, AlVI
  • 2 Gaussian lines each having 2 spinning sidebands for the satellite transitions of AlIV and AlV


2D Fit

Load the 'CaAlGlass.rr' file by [File/Open], by dragging the file to dmfit or by double clicking if configured.

switch to Contour plot if needed
