通过计算自相关函数和交叉角相关函数,比较了UGC和ESO光学星表中星系的分布与IRAS样品中星系的分布。据发现,每个角相关函数是很好地近似的形式w(θ)= A(θ exp 1-γ)的角距离为5度,γ = 1.7。参考文献32篇。
The galaxy distributions in the optical catalogs UGC and ESO are compared with those in the IRAS sample by calculating the auto- and cross-angular correlation functions. It is found that each angular correlation function is well approximated by the form w(theta) = A (theta exp 1-gamma) out to an angular distance of 5 deg, with gamma = 1.7. 32 refs.
