"A Pedagogical Approach to the Generalised Fitting Error in MCAO"

Multi-conjugate adaptive optics (MCAO) aims to overcome the problem of anisoplanatism, allowing astronomers to access large regions of the sky with good adaptive optics correction. A source of error unique to MCAO systems is the generalised fitting error, which is a consequence of the finite number of deformable mirrors available to correct for a continuous turbulence profile. I will present my work on a pedagogical approach to understanding the generalised fitting error and demonstrate the use of such an approach in analysis of MCAO design.
