Median distance from the nearest filament spine of BGGs selected in density bins of constant width . The panels show (a) red and blue, (b) high and low mass, (c) elliptical and spiral, and (d) high and low D4000 BGGs. Only bins with at least ten BGGs are shown. The thicker coloured error bars are 65% and the thinner black bars are 95% confidence intervals calculated using bootstrap resampling. Differences in filament distances are minor and none of the populations are consistently closer to or farther from filament spines.
