Lineshape does not meet spec. Needs 3D Gradient shimming. Found that the upper barrel was not centered in magnet field. Re-centered upper barrel. Performed 3D gradient shimming successfully. Obtained lineshape spec after RT shimming. Performed H1 and C13 performance specs, all passed. Default shims and power level vales saved. New gradient map saved.
