This is pretty standard to apply these same measurements to each line just changing the value. I'm sure you could google an explanation. Try checking out the NHC website and the recon link. I'm sure they have something on there, although I haven't looked for anything like that in a long while.

Hope this helps. If you have any more questions just ask. And, mets, if I made any mistakes please let me know.

edit: Clark finished before I did. Sorry, I'm at work. His is much easier to understand so look at his instead.
