a) Individual Gaussian peaks A, B, and C (——) and the detected signal from them (——). b) As in a), but with peak A shifted until two observed peaks (maxima) are barely observed. Axes are scaled as in a). c) As in b) but peak C is absent. d) Graph of the average minimum resolution $R_s^{\ast }$ vs. the saturation α for 1D separations ( $R_{s,1D}^{\ast }$) and 2D separations ( $R_{s,2D}^{\ast }$).
