Multispot γ factor.

Line 1–3: multispot γm values and their obtained from Table 5 and Fig 2, using Eq. (SI.61) with PR estimates obtained by Gaussian fit, KDE or SNA, respectively. Values computed for samples 22d and 27d (indicated in italics) are unreliable due to the overlap between DO and DA PR peaks. Last line: factor K (Eq. (SI.65)), proportional to the uncertainty on γm, computed for the Gaussian fir approach. Values for the other methods are comparable. A common set of parameters ds = 0.061, βs = 0.81, lm = 0.033 was used, average of the values obtained with the various analysis methods.
