FSD window set point for 15 deg dipole (MDR1I02 Low Noise Supply) for 140 kV Gun operation is updated.

Crew chief changed the MDR1I02 setpoint from -2.6 A to -2.08 A.

Max Bruker provided the new set point for 140 kVas -2.08 A. High and low limits are set as 20% of the nominal per Joe Grames instruction.

Per Scott Higgins request he is been notified about this change.
