1  ATLAS 2022 report combined results (see their Extended Data Table 1) using up to 139 fb${}^{-1}$ of data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV, assuming ${\mathit m}_{{{\mathit H}}}$ = 125.09 GeV. Coupling strength modifiers including effective photon, ${{\mathit Z}}{{\mathit \gamma}}$ and gluon are measured. See their Fig. 6.
2  ${{\mathit B}_{{{inv}}}}$ = ${{\mathit B}_{{{undetected}}}}$ = 0 is assumed.
3  ${{\mathit B}_{{{inv}}}}$ floating, ${{\mathit B}_{{{undetected}}}}{}\geq{}$ 0, and ${{\mathit \kappa}_{{{V}}}}{}\leq{}$ 1 are assumed.
4  CMS 2022 report combined results (see their Extended Data Table 2) using up to 138 fb${}^{-1}$ of data at $\mathit E_{{\mathrm {cm}}}$ = 13 TeV, assuming ${\mathit m}_{{{\mathit H}}}$ = 125.38 GeV. Coupling strength modifiers including effective photon, ${{\mathit Z}}{{\mathit \gamma}}$ and gluon are measured. See their Fig. 4 left.
