HBOOK is a Fortran
callable
package for histogramming and fitting.
It was originally developed in the 1970s and has since
undergone continuous evolution culminating
in the current version, HBOOK 4.
Many people have contributed to the design and development of HBOOK, through discussions, comments and suggestions.
Paolo Palazzi was involved in the original design. D. Lienart has been in charge of the parametrization part. Fred James is the author of routine HDIFF and of the minimization package Minuit, which forms the basis of the fitting routines. The idea of Profile histograms has been taken from the HYDRA system. The Column-wise-Ntuple routines were implemented by Fons Rademakers. The multi-dimensional quadratic fit package HQUAD is the work of John Allison. J. Linnemann and his colleagues of the D0 experiment contributed the routine HDIFFB. Pierre Aubert is the author of the routines to associate labels with histograms. Roger Barlow and Christine Beeston (OPAL) have developed the HMCMLL package.
