Fig. 4: Extracting relative height differences using relativistic gravitational potential measurements.
From: A lab-based test of the gravitational redshift with a miniature clock network
The relative clock height differences across the array are determined using the measured gravitational redshifts and the independently measured local gravitational acceleration g. The double arrows represent the extracted height difference and the associated uncertainty for each clock pair. The true clock heights are shown on the right (red values), with the lowest clock (clock 5) defined as being at a height of 0 cm. All units are in cm unless otherwise specified. The uncertainties correspond to 1σ standard deviation.
