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

除了通称为游不规律星体外，恒星和卫星间视折光微小，而且是容易。

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.
