The parallactic refraction between the stars and the satellite is small and well determinate, except for the irregular stellar movements known as erratics.

除称为游动的不规律星体运动之外，恒星和卫星之间的视折光微小，而且是容易测定的。

Said image pair with parallactic information can also be inputted to the computer by scanning equipment or can be formed by adopting computer three-dimensional animation software.
