壳型信噪比的银河系分布的结果得到，使用经验得出的校正因子来考虑选择效应。其空间分布在距银河系中心4-6 kpc处有一个峰值，与约翰逊和麦克劳德（1963）对螺旋星系SN的结果相似。利用考克斯（1979）模型，在约50%的不确定性下，平均信噪比年龄为6800年。对与SN率一致的SNR出生率施加约束。
Results for the Galactic distribution of shell-type SNRs are obtained, using empirically derived correction factors to account for selection effects. The spatial distribution has a peak 4-6 kpc from the Galactic center, and is shown to resemble that obtained by Johnson and MacLeod (1963) for spiral galaxy SN. Using the Cox (1979) model, an average SNR age of 6800 yr is found with about 50 percent uncertainty. Constraints are placed on the SNR birthrate which are consistent with the SN rate.
