The manipulation of data within BoA is done with objects of the
DataEntity class (see also Section ).
One object of this class is stored in the currData attribute
of the BoaB object; this is the current object, on which all
reduction procedures can be applied.
Additional objects of this class can be created
by the user.
The definition of DataEntity objects enables to store the raw data and the reduced data, as well as associated parameters, as described below.
