All mass shifts for which the mass difference between network pairs was within the error of known chemical groups

Mass shifts are shown separately based upon whether they putatively involve oxygen (blue) or only carbon and hydrogen (red). Reported are the mass shifts observed in the real data (Obs. mass), the calculated mass shift of the known mass shift (Calc. mass), the percentage of all mass shifts representing that mass shift (% mass shift), and the putative element or group composition.
