spectrum, dynamic range
The value is a floating point number Drange > 1.0
This parameter is used to normalize the intensity values of fragment ions, from spectrum to spectrum. For example, if Drange = 100.0, then the intensity of the most intense peak in a spectrum is set to 100, and all of the other intensities are linearly scaled to that intensity. Any peak with a scaled intensity of less than 1 is rejected as being outside of the dynamic range. Therefore, in addition to normalizing the spectra, it sets an effective relative threshold for peaks.
