Continuous g measurement on December 12, 2018. (a) The black points indicate the measured data of g, each datum is an average of g measurement over atom falling of 900 times (approximately 298 s). The red line is the calculation from the Earth tide model. The residue shows the difference between the measured g and the tide model. (b) Allan deviation of the g measurement with and without tilt drift correction.
