In a mass spectrum, the observed [[m/z]] value divided by the smallest difference ?(m/z) for two ions that can be separated: (m/z)/?(m/z).  
  
 
Note 1: The m/z value at which the measurement was made should be reported.

Note 3: Alternatively ?(m/z) is defined as the separation between two adjacent equal magnitude peaks such that the valley between them is a specified fraction of the peak height, for example as measured by peak matching.
