Instrumental systematics and weak gravitational lensing
  We present a pedagogical review of the weak gravitational lensing measurement
process and its connection to major scientific questions such as dark matter
and dark energy. Then we describe common ways of parametrizing systematic
errors and understanding how they affect weak lensing measurements. Finally, we
discuss several instrumental systematics and how they fit into this context,
and conclude with some future perspective on how progress can be made in
understanding the impact of instrumental systematics on weak lensing
measurements.
