Fraction of light in IGL compared to the total group light (f_IGL) of the KiDS+GAMA groups at different redshifts from the 0^th order (p₀) background-subtracted images. f_IGL from this work along with previous works on individual galaxy groups and clusters (grey markers). The x-axis indicates the mean halo mass M_h of the host systems (previous works) or the corresponding bins (this work). Pink, yellow, and cyan shaded regions show the upper and lower limits of f_IGL for the redshift ranges 0.09 < z < 0.15, 0.16 < z < 0.21, and 0.21 < z < 0.27, respectively.
