Data processing for 1D, 2D and 3D data files

This programs allows to process 1D, 2D or 3D data. 2D data correspond to data measured on a Position Sensitive Detector. 3D data correspond to data measured on a PSD and with a time resolution (either Time of Flight or Time resolved experiment). This typically applies to TOF neutron reflectivity or time resolved SANS measurements. This program allows to perform standard operations such as masking, integration, fitting. A "macro-language" allows to automate data processing.
