Specifications for the field quality of the LHC closed orbit correctors and sextupoles

The field quality of the LHC closed orbit correctors and sextupoles is specified by comparison with the acceptable multipole content of the main LHC quadrupoles and dipoles. The latest error tables corresponding to a positioning accuracy of the coils of 0.1 mm are found to be within tolerance. This note describes the methods and critetia in some detail to serve as a template for the analysis of the tolerances of other correctors.
