This work compiles measured and derived values of coefficients for Lorentz and CPT violation in the Standard-Model Extension (SME). Summary tables are extracted listing maximal attained sensitivities in the matter, photon, neutrino, and gravity sectors. Tables presenting definitions and properties are also compiled. The paper includes 46 data tables, 25 properties tables, and four summary tables. The data tables include results from experimental measurements and theory-derived limits. Each data table provides information about searches for Lorentz violation in specific sectors of the SME. The summary tables list best estimates for maximal sensitivities to relevant SME coefficients in the corresponding sectors. The properties tables list features and definitions of the SME and coefficients for Lorentz violation. The paper also includes definitions of operators and their properties under discrete spacetime transformations. The SME is a general effective field theory for Lorentz violation that includes the Standard Model coupled to General Relativity along with all possible operators for Lorentz violation. The SME also describes general CPT violation. The paper discusses the classification of Lorentz-violating operators according to their mass dimension and provides definitions of coefficients for Lorentz violation. The paper also discusses the minimal SME, which includes only Lorentz-violating operators of mass dimension four or less. The paper provides information about the physical sensitivities, using natural units with ħ = c = ε₀ = k_B = 1 and expressing mass units in GeV. The paper also discusses the organization of the tables and the conventions used in the tables. The paper includes information about the format and content of the data tables and the properties tables. The paper also discusses the conventions used in the tables and the definitions of the coefficients for Lorentz violation. The paper provides information about the physical context of the bounds and the source citations. The paper also discusses the relationships between the coefficients and the operators in the SME. The paper includes information about the properties of the coefficients under discrete spacetime transformations and the relationships between the coefficients and the operators in the SME. The paper also discusses the implications of the results for future searches and the open directions for future searches.
