The on-the-fly setpoints can all be used as a vernier to scan around the setpoint.
The on-the-fly setpoints are:
DL1 Energy: The desired Energy for Dog Leg 1, in MeV.
...
DL2 Energy: The desired Energy for Dog Leg 2, in MeV. This is most often used as a 'vernier' around the actual DL2 Energy value.
The setpoints that can be changed when the feedback is off are:
L2 Chirp: use this PV when the feedback is inactive, the same as you would the L2 Chirp MeV PV on Joe's display.
