HBOOK/PAW

HBOOK and PAW are CERN Library software packages which are used by SNOMAN to facilitate the non-graphics display of output. HBOOK handles statistical distributions, mainly histograms or N-tuples. An N-tuple is simply a vector of data words which are stored on an event by event basis and then written to a file at program termination for later analysis. This analysis is done using the program PAW, which allows the user to interactively perform a large number of different procedures (2-D and 3-D plotting, histogramming one variable in an N-tuple subject to cuts on one or more others, even fitting the resulting distributions using the CERNLIB routine MINUIT). In the examples given in the operating instructions we will show a few simple manipulations of the output of SNOMAN using PAW just to get people started. For more details the reader should consult the PAW and HBOOK manuals, available free of charge from the CERN Program Library (send requests to CERNLIB@CERNVM), you want Q121 (the PAW manual) and Y250 (the HBOOK manual), and you might as well get a CERN program library manual while you are at it.
