Couplers

[BigPeter]

After trying to position couplers without much success due to very poor eyesight, I found that in my wagon XML I now have 4 entries , 2 for each coupler pivot point and 2 for each coupler receiving point.

Is it possible to find out what each line does and enter the coupler position manually with the correct figures.?

I have determined the 14th and 15th lines are height of coupler and distance from center.
The entry below shows other figures, but I think I twisted the coupler when trying to place the coupler in asset editor.
