Materials Required

  • Sight reduction worksheet for direct calculation
  • Scientific calculator

 


Homework Assignment

  • Create a sight averaging plot from sights 3, 4, 5 and 6 from this list.


  • Complete the sight reduction of sight #3, from 12:48:39, and plot it on this plotting sheet.
