          Args::
  
            cal         the calibraton factor (attribute 'scale_factor')
            cal_error   calibration factor error
                        (attribute 'scale_factor_err')
            offset      offset value (attribute 'add_offset')
            offset_err  offset error (attribute 'add_offset_err')
            data_type   data type of the values resulting from applying the
                        calibration formula to the dataset values
                        (one of the SDC.xxx constants)
                        (attribute 'calibrated_nt')
  
          Returns::
  
            None
  
          See method 'getcal' for the definition of the calibration
          formula.
  
          Calibration coefficients are part of the so-called standard
          SDS attributes. Calling 'setcal' is equivalent to setting
          the following attributes, which correspond to the method
          parameters, in order::
  
            scale_factor, scale_factor_err, add_offset, add_offset_err,
            calibrated_nt
