The E and F coils are combined when loading from the EFIT tree. However, the F coils have the turns multiplied with the current, which one could argue is an preexisting error in MDS+. This would be at least consistently wrong but the F-coils are combined with the E-coils in pf_current in constraints which are stored correctly.
Following options:

• Merge this and remove the mapping completely
• Try to fix the mapping, but this is tricky because the information on how many windings each coil has is not MDS+. For DIII-D there is some expectation that the F-coils always have the same amount of turns for all shots, but the EFIT tree and mapping is not DIII-D specific, so it gets complicated very quickly.
• Leave it because it is consistent how the code wants its pf_currents. Here it is important to remember that this is the mapping for EFIT not the mapping for pf_active.
  I leave it to @smithsp to make an executive decision and @bechtt to add his own opinion.
