The identification of each serovar is derived from the combinations of the 5 discriminating considered peaks.
+: peak with area/intensity of the Serovar Average Spectrum higher than the Total Average Spectrum for the respective considered peak.
-: no peak found.
§: peak with area/intensity of the Serovar Average Spectrum lower than the Total Average Spectrum for the respective considered peak.
