• To better accept the Sigma-hyperon within our acceptance, Joerg Reinhold had found that we should change the electron momentum by dropping it by about 1%. As of 1-24-01, we have done that.

• In December 2000 John LeRose investigated the maximum momentum of the HRSR. The maximum current in the Right Dipole of 1135.19 Amps corresponds to 3.1447 GeV/c.
• At 5.618 GeV incident beam energy, we will first run the four Q²=2.35 (GeV/c)² points, then the LT-interference points, and finally the four Q²=1.90 (GeV/c)²
