5D histogram package NORA

The presented software package is an advanced analogue of the famous HBOOK and, in part, ROOT packages. The main features of the package are as follows. Standard operations (accumulation, simulation, transformation) are extended up to 5D objects. A new type of transformations of objects has been introduced, the x-transformation, which includes convolution of distributions. Objects are accessed mainly by alphabetical name. The formation of the object space is carried out using a data file, where the user can choose the form of setting attributes. Automatic adjustment of object attributes is possible (only the number of channels is set). The number of channels for each of the axes of the object is unlimited. Operations between two objects (addition, subtraction, etc.) are possible with mismatched attributes. Data output is carried out in two forms, for graphics and for fit. Group operations are provided for visualization, outputting files for graphics. All programmes are written in FORTRAN-90. The investigation has been performed at the Veksler and Baldin Laboratory of High Energy Physics, JINR.
