==== Step L2: Delta Scan with Proton Elastic (sieve) ====
The DVCS calorimeter HVs need to be off
If the LHRS goes to a higher momentum setting, Q2 and Q3 need to
be cycled.
LHRS θe=16.5 deg
Rate: 13.3 kHz at 20 μA (taking into account the sieve). Electron rates only.
We are going to need to take these data at about 1 μA.
Run duration about 10 minutes each (we want at least 10k events).

==== Step L3: Carbon elastic ( no sieve) ====
A. Camsonne needs to be called to remove the sieve at the beginning to the program.
The DVCS calorimeter HVs need to be off
If the LHRS goes to a higher momentum setting, Q2 and Q3 need to
be cycled.
P0= 2.281 [GeV/c] (super-elastic)
Estimated rate: 0.7 Hz at 20 μ
Single Carbon foil or Optics target.
No raster
3 hours.
==== Step L4: Tungsten wire ====
This part of the program is to be run in parallel with the RHRS run plan (Step R5)
The DVCS calorimeter HVs need to be off
If the LHRS goes to a new higher momentum setting, Q2 and Q3 need to
be cycled.

- Optics target
When going up in momentum, Q2 and Q3 need to be cycled, Q1 doesn't need to be cycled.
Set p0=1 GeV. Q2, Q3 and the dipole need to be momentum regulated. Take Q1 off the regulation.
5 optics foils target.
5 u A unrastered (if the rates are too high use rescales or decrease the current). Take 100 k events at :- Q1= 1672.4 A (tuned)

When going up in momentum, Q2 and Q3 need to be cycled, Q1 doesn't need to be cycled.
Set p0=2.224 GeV. Q2, Q3 and the dipole need to be momentum regulated. Take Q1 off the regulation.
