Example of a 2D image used for interferometric simulation. The synchrotron and SZ emissivity models are placed on a spherical shock and projected, on top of a cluster-wide SZ signal that follows the GNFW pressure model. In this case the relic is viewed edge-on (0° inclination angle). The full-spherical shock model for SZ is obvious, although for our purposes of computing flux contamination it is sufficient for the SZ signal boost to be localized in the same angular segment as the radio relic emission.
