SLGLAO
The movie below shows dynamical simulations of the wavefront phase of
a science target after subtraction of the wavefront phase from a laser
guide star at 90 km altitude. The corrected wavefront phase displays
residual error due to focal anisoplanatism. This displays a SLGLAO-like correction. The simulation assumes a 10 meter telescope observing through a Cerro Pachon turbulence profile, with r0 = 15 cm at .5 um.
