DeltaG

Delta-G(t) is the time-series of the differential spurious force per unit mass acting on the two Test-Masses (TMs) on board LISA Pathfinder (LPF) along the axis joining them. It quantifies the purity of the TMs free-fall tested by LPF and represents the most important outcome of the mission. All the data is available in the form of xml files. The use of the ltpda data analysis package is recommended for reading and manipulating the data.
