Extended Data Fig. 1: Line shape curve fits.
From: Precision spectroscopy of the hyperfine components of the 1S–2S transition in antihydrogen
Fit of the line shape function described in the text to a simulation of the d-d transition with 1300 mW laser power and no laser cooling, normalized to the fit height. Shown are 14 individual simulations each exposing a trapped sample to 9 detunings near the values used in the runs 1 and 2. The χ2 of the fit is 194 with 120 degrees of freedom. The plotted uncertainties represent one standard deviation counting errors.
