Systematic uncertainties study for D0 paper - Guannan Xie
slide 5: nHitsFit systematic errors go in opposite direction in central and peripheral collisions.
They will hence not cancel out in Rcp.
slide 8,9: Averaging HIJING cut1 and cut2 for central value ay not be a good choice since cut2 is much worse in describing
vertex resolution.
slide 10: The first and last point should also be included in the table of systematic errors.

slide 5: Check also 3 iterations for estimation of systematic errors.
slide 6: Old embedding which is know to have problems was used. Needs to be redone with a new one.
slide 9: The fits may have failed - needs to be checked
side 10: The bin shift should not be included in the systematic errors.
slide 14: The pt smearing should also be excluded from syst. errors.
