/** BmnFieldMapData.h
 ** @author V.Friese <v.friese@gsi.de>
 ** @since 14.02.2006
 ** @version1.0
 **
 ** This class holds the real data arrays of a magnetic field map,
 ** which are read from / written to file. Nota bene: Field values
 ** are in Tesla, in contrast to BmnFieldMap, whcih holds the
 ** field in kG.
