Abstract

For a segmented primary mirror consisting of 7 segments organized in 1 concentric hexagonal band around the central segment, of which the point spread function (PSF) is represented by the product of the grid function (GF) and the PSF_j of an individual segment. The system PSF and Strehl ratio given for the cases of the gaps or piston errors are present.
