即将发射的美国航天局伽马射线观测站侧重于需要提供远离银道面的星际辐射能量密度的最新估计，这一参数是计算宇宙射线电子逆康普顿相互作用产生的伽马射线通量的先决条件。作者利用恒星分布和星际介质中尘埃的消光特性的信息进行了这样的计算。随后的能量密度可能精确到约30%，不确定性是由于缺乏输入参数的精确知识，而不是计算中的近似值。
The imminent launch of the NASA Gamma Ray Observatory has focused on the need to provide up-to-date estimates of the energy density of interstellar radiation away from the galactic plane, this parameter being a prerequisite for calculation of flux of the gamma-rays coming from the inverse Compton interactions of cosmic ray electrons. The authors have made such calculations, using information on stellar distributions and on the extinction properties of dust in the interstellar medium. The ensuing energy densities are probably accurate to about 30%, the uncertainty being due to lack of precise knowledge of the input parameters rather than approximations in the calculations.
