Projected spatial offset plotted against broad to narrow emission line velocity offsets (absolute value) in recoiling BH candidates. The color scale reflects the bolometric power of each object. Blue is used for L_bol< 10⁴³ erg s^-1, yellow for 10⁴³<L_bol< 10⁴⁵ erg s^-1 and red for L_bol> 10⁴⁵ erg s^-1. For SDSS1133 the velocity offset is known to vary between 40 km s^-1 and 1890 km s^-1 (Koss et al. 2014). In this figure we use the measurement corresponding to the highest velocity.
