    • In this context, a major product might be a star, a star-star couple or an initiator terminated star, and must have a high abundance. Precisely which of these are deemed to be major depends on the region of the mass spectrum, which is of interest. For instance, certain spectral regions in a given mass spectrum might have ideal stars as the most abundant well known peak whilst for other spectral regions this might be star-star couples

    • In a mass spectrum, peaks labeled as nonrepeating have been found to occur only once, that is, not at periodically spaced m/z intervals of 162.07 Da, the mass of AcOSty monomer. Consequently, these peaks are unlikely to correspond to poly(AcOSty) material but rather are deemed to be impurities existing within the sample. These peaks typically disappear upon repeating the mass spectrometric analysis. 56. The normalized experimental noise was estimated by hand-picking the apex of a representative peak in a region that contained only a background signal and comparing this abundance value with that of ideal stars

The normalized experimental noise was estimated by hand-picking the apex of a representative "peak" in a region that contained only a background signal and comparing this abundance value with that of ideal stars.
