Fringe contrast (T = 203 ms) versus mirror’s rotation rate. The influence of the detector was not considered here. The dash-dot line is for atoms with temperature of 10 nK, the rotation compensation is not obvious. The dot line is for 0.3 μK atoms, the rotation compensation is effective in the range of –4Ω₀ to + 2Ω₀, the solid line is for 3 μK atoms, the rotation compensation is effective in the range of –1.5Ω₀ to + 0.5Ω₀.
