Modules are available which provide:
- User configurable multi-line/symbol plots
- User configurable area (contour, image) and surface plots
- Ability to rebin, scale, and shift individual datasets
- Make 1D slices/cuts of 2D data
- Merge/combine multiple 1D/2D datasets into a single 2D dataset
- Print or generate hardcopy output in postscript and other image (jpeg/png/bmp/tiff) formats
|
The following data analysis tasks can be performed:
- General-purpose least-squares fitting of 1D/2D data using 1D model functions
- General-purpose least-squares fitting of 2D data using 2D model functions
- A large selection of model functions (1D and 2D) are included
- Possible to specify user-defined functions (1D only)
- Ability to include instrumental resolution function in the model functions
- Fitted parameters and results can be analyzed and saved as ASCII data and/or hardcopy plots
