Estimation errors for ∆[cj], where cj represents the jth chromophore with j = 1, 2, and 3 corresponding to (a) HbO2, (b) HHb, and (c) oxCCO, respectively. Time points i are in minutes. The dataset considered here is the same as the one shown in Fig. 2 and the errors for each k-wavelength combination listed in Table 1 are plotted only over the period of HI.
