What does it mean ?

I have a doubt related this resource.
I got this code and would like to know what does it mean ? The coords -49, -12 are the same in four blocks, I changed others, that are in the north, south , east and west of the coord -49, -12.

How to analize the result ?
What are the numbers in the result ?

  bearing NUMBER;
  tilt NUMBER;
