a) MH+ Peptide masses; b) Z Charge value of each peptide; c) P(pep) Probability of finding a match as good as or better than the observed peptide match by chance; d) XCorr the cross-correlation value from the search, used to produce the final ranking of the candidate peptides in the search. XCorr values above 2.0 are indicative of a good correlation.
