CDF of the absolute value of the height above the Galactic plane, |z|, for SNRs originating from CCSNe (solid line) and SNe Ia (dashed line). The vertical dotted line is at 1 kpc. The CDF of SNRs originating from CCSNe is normalized to 28, as the rate of CCSNe is 28 times higher than that of SNe Ia. As SNe Ia from the thin disk are excluded from this calculation, only the difference for |z|≥1 kpc should be observed.
