  The LISA Pathfinder (LPF) mission succeeded outstandingly in demonstrating
key technological aspects of future space-borne gravitational-wave detectors,
such as the Laser Interferometer Space Antenna (LISA). Specifically, LPF
demonstrated with unprecedented sensitivity the measurement of the relative
acceleration of two free-falling cubic test masses. Although most disruptive
non-gravitational forces have been identified and their effects mitigated
through a series of calibration processes, some faint transient signals of yet
unexplained origin remain in the measurements. If they appear in the LISA data,
these perturbations (also called glitches) could skew the characterization of
gravitational-wave sources or even be confused with gravitational-wave bursts.
For the first time, we provide a comprehensive census of LPF transient events.
Our analysis is based on a phenomenological shapelet model allowing us to
derive simple statistics about the physical features of the glitch population.
We then implement a generator of synthetic glitches designed to be used for
subsequent LISA studies, and perform a preliminary evaluation of the effect of
the glitches on future LISA data analyses.
