Previously Planned Coverage. 57 days : Septa In 54 days : Septa Out 42 days : Transition. Delay to Feb 1 => loss of 55 days. What we can do with late start & Hall B coils. Lose 2 highest Energies =>g2p oses 1 Q 2 point =>GEp loses overlap extend 2.2 Gev bands to large W

Previously Planned Coverage 57 days : Septa In 54 days : Septa Out 42 days : Transition Delay to Feb 1 => loss of 55 days
What we can do with late start & Hall B coils Lose 2 highest Energies =>g2p oses 1 Q2 point =>GEp loses overlap extend 2.2 Gev bands to large W Spend additional time on elastic
83 calendar days of running +14 days of commissioning (Maybe can do some of the beamline commissioning before target is in?)
Impact on E08-027 Projection for the LT spin polarizability
Impact on E08-027 We lose the highest interpolated Q2 point
Impact on E08-007 Projection for GEp/GMp with new running constraints Lose overlap with large Q2 run.
Summary Assuming Hall B coil package will be scavangeable and GEp runs at 7 degree instead of 20. Reduced target region of uniformity: 3 -> 2 cm DSV Adding in some extra kinematics for g2p at large W We can achieve the bulk of the physics goals of E08-027 and E08-007 E08-027 loses one Q2 point E08-007 loses the overlap with high Q2 data. 8.6 additional days at 1.1, 1.7 GeV will need to run oppurtunistically
