Optics

Telescope and camera optics.  LSST will use active optics informed by curvature wavefront sensing (CWFS) to maintain a nearly static and optimal optical PSF.  Understanding the residual optical aberrations and associated uncertainties will be important for constructing the global PSF model. The CWFS system will also aid in reconstructing the PSF likelihood over the focal plane due to atmospheric distortions at positions other than the calibration stars.
