Contamination predictions for a set of double relics in ten galaxy clusters, for whom the edge-on geometry can be applied with reasonable confidence. The relic dimensions and flux measurements are compiled by de Gasperin et al. (2014) and Vazza et al. (2015); the SZ predictions are calibrated against actual Y₅₀₀ values derived from Planck data. The blue dashed line is the mean contamination prediction from our modeling (see Sect. 3.1.1), using the mean cluster mass and shock parameters for this sample. Red dot-dashed lines connect the relic pairs for easier identification.
