(a) Schematic diagram of the calibration basket and threads attached to the thrust balance. (b) Displacement signal of the laser sensor when putting a known mass to the basket at about every 20 sec (a gray line), together with a filtered signal (solid red line). (c) The relation between the applied horizontal force and the measured displacement (open circles), together with a fitted line (thin blue line) giving the calibration coefficient.
