The circuit diagram of the magnets can be found here:

• The main bus current ( ~ "IF" in the above circuit diagram) :




 

Each current described below is the sum (or actually subtraction) of the two input lines going into that magnet.

• The bus current going into Q1 :





• The bus current going into Q2 :




• The bus current going into Q3 :






 

 

The following is the dipole bus current which was plotted "by mistake".  But since it's made, I don't want to waste it :
