Summary
RXC J1314.4-2515 is one of the better representations of double relic systems. Valtchanov et al. (2002) obtained 37 spectroscopic redshifts of cluster members and found that there is a significant bimodal distribution in redshift space (~1700 km/s separation) and is supported by a bimodal distribution of galaxies in projected space. The double relics have been observed on VLA and GMRT (Feretti et al. 2005; Venturi et al. 2007; Venturi et al. 2013), although little work has been done studying the spectral steepening or polarization. Mazzotta et al. (2011) briefly reported on their analysis of XMM-Newton data (106 ks), and found a shock front consistent with the leading edge of the western radio relic. They note that there is excellent agreement between the Mach number estimates of X-ray and Radio. Interestingly this shock front is M-shaped which they suggest may indicate infalling material.
