Figure2: The line (the range) where they have lived

If considered that THEY might see the different location of the tri-star, the lines that THEY can see a true tri-star are spread about 60 light  year away, and the  range is changedwithin 692 light year around (but this may be little irregular). If Monocerus people or Taurus people might exist, THEY might live in 66 light year  away (Aldebaran), or 150 lightyear away (Hyades cluster), but not β-Monocerotris (700 light year away).
