Table 2
Angular size for two critical comoving sizes: 10 h-1 Mpc and the BAO standard ruler of 150 h-1 Mpc.

Notes. Since they are expanding, the angle does not stay constant as it does for the simple fixed physical distance of 10 Mpc. The comoving angle reaches relatively constant value at higher redshift. The cosmology assumed here is a flat Universe with Ωm = 0.3036 and H0 = 68.34 km s-1 Mpc-1.
