Notes. The values listed here are the fiducial mean and median SOM bias obtained from SKiLLS (Sect. 6.1.1), followed by the shift-fit parameter obtained by fitting the CCs with the SOM redshifts, and finally the difference between the median SOM bias and the shift-fit parameter. The uncertainties of δz_mean and δz_med are identical to the third decimal place after applying the error floor. $D_{z}^{SOM}$ $D_{\mathrm{z}}^{\mathrm{SOM}}$ is duplicated from Table 7 for comparison.
