270
280
160
110
180
310
140

310

210
330
310
320
This is assuming conventional azimuth measurements. In the image I've included what the results would be if based on the layout of a circle protractor (assuming 0 is up), just in case!
If this is heading in the right direction, what do we do with these numbers?
