Abstract
The Laser Interferometer Space Antenna Pathfinder (LPF) main observable, labeled ¿g, is the differential force per unit mass acting on the two test masses under free fall conditions after the contribution of all non-gravitational forces has been compensated. At low frequencies, the differential force is compensated by an applied electrostatic actuation force, which then must be subtracted from the measured acceleration to obtain ¿g. Any inaccuracy in the actuation force contaminates the residu...
