Application of Equation 24(a) from Jenkins (2009), used to estimate the depletion strength factor F_* and N(H_tot) from the relative depletions of various species, for the main component toward HD 62542 (left panel) and the other components (right panel). The y values are derived from the column densities of the dominant species listed in Table 3, the protosolar abundances from Lodders (2003), and the coefficients derived by Jenkins (2009) and Ritchey et al. (2018). The x values are the corresponding A_X coefficients from the latter two references. The depletion factor is given by the slope of the fitted line: 1.52 ± 0.19 for the main component and 0.28 ± 0.10 for the other components. The estimate for log (N(H_tot)) is given by the y value of the line at x = 0.0: 21.25 ± 0.19 for the main component and 20.16 ± 0.13 for the other components.
