Constraints on the explosion sites of the six SNRs targeted in this paper. We show exposure-corrected images of the SNRs (with logarithmic intensity scaling), overlaid with 1σ and 2σ contours for the most likely origin of the CCO. The apparent geometrical centers of G15.9+0.2 (estimated in this work), RX J1713.7−3946 (Pfeffermann et al. 1996) and G350.1−0.3 (Lovchinsky et al. 2011) are indicated with white crosses. For Cas A, we plot the precisely constrained expansion center from Thorstensen et al. (2001) in an inset to make it more easily distinguishable. All images were created from the Chandra data used in this work, except for RX J1713.7−3946, where we used an archival ROSAT observation.
