Table 5.

The number of spectra within each realization of sampling

Data	LTQ/LTQ	LTQ/FT	FT/FT	TOF/TOF
MAX1 (U)	162(24)	43(16)	49(18)	20(18)
MAX2/SUM2 (U)	324(48)	86(32)	98(36)	40(36)
MAX3/SUM3 (U)	486(73)	129(48)	147(54)	60(54)

The first number in the table is the number of compound spectra per realization of sampling when mixing spectra in the co-identifiable set. The number in parentheses is the number of compound spectra per realization of sampling when mixing only spectra of unique peptides (see text for more detail). The symbol "U" inside the parentheses stands for "unique peptide."
