Q3 of R-HRS can only set to about 2.8273GeV/c while we require the center momentum of R-HRS run upto 3.155 GeV/c, so we basically scale down Q3 momentum by applying a ratio of 2.8273/3.155 on Dipole momentum. This treatment should give us a uniform Optics matrix for every kinematics setting.

Optics Data we took: 

1), Momentum Scan at QE: E0 = 3.356,Beam = 20uA, Theta=23.00, P0_R=2.600, RQ3_0=2.2808, Target=Dummy 4cm, Raster=On
 a)Run#3695: +3%, P_R=2.678, RQ3=2.3492, 500K events 
 b)Run#3698:  0%, P_R=2.600, RQ3=2.2808, 576K events 
 c)Run#3704: -3%, P_R=2.522, RQ3=2.2124, 426K events 
2), Vertex Scan Data at QE: P0_R=2.600, RQ3=2.2808, Theta=23.00
 a)Run#3699: BeO, single foil Target, Raster=Off, 400K
 b)Run#3700: Multi-C 15cm, 7-Foils, Raster=Off, 400K
 c)Run#3701: Multi-C 15cm, 7-Foils, Raster=On, 400K
3), Sieve Data at QE: P0=2.505, RQ3=2.1975, Theta=25.00 -- Optics / 50 uA on Ca48 / Raster Off / Kin 5.05
