Left: fringe pattern obtained in a single-cloud interferometer, with a time T = 160 ms between Raman pulses; each point represents a single measurement; the continuous line is a least-square fit to the data using Eq. (2) after determining the A and B parameters from Eq. (3) . Right: histogram of measured data; dashed line is a least-squares fit to the data using Eq. (3) .
Reconstructed fringes for T = 160 ms: the measurements and from the two simultaneous interferometers are plotted versus the calculated phase ; each fringe contains 1800 experimental points, and each point represents a single measurement; in (a), the phase is computed from the upper interferometer by applying Eq. (4) after determining A and B with Eq. (3) ; in (b), is computed with Eq. (5) .
Variation of Earth's gravity as a function of time. Each dot is obtained by averaging the measured data over a 1 h interval. Error bars represent the statistical error. The solid line is a fit to predicted Earth's tides with a baseline as the only free parameter.
