Red-sequence models for the six different calibrations (rows). Each filter band combination and LS parts are labeled in the titles of the subpanels. The combination of n filter bands results in red-sequence models for n − 1 colors (columns). The red-sequence models are shown by the red splines and red points mark the spline nodes. The training galaxies are color-coded according to their point density. Their total numbers are, after clipping, ~93 000 for LS DR10 (grz and grzw1), ~72000 for LS DR10 (griz and grizw1), and ~36000 for LS DR9 north (grz and grzw1).
