Caption: Figure 8.

Fraction of misaligned gas–star PA for BGGs residing in groups with a varying luminosity gap, ΔM₁₂ (right), and BGG offset, D_offset (left). Colored lines show the trend for three stellar mass bins. Black dashed lines show the median trend for all BGGs in our sample. Errors (color-shaded lines) are 1σ confidence intervals on the fractions calculated by the bootstrap method. Gray vertical dashed lines in each panel show the selection for low/high offset and high/low gap groups.
