| Abstract: | The Shack-Hartmann(S-H) method, a common technology for measuring the ray aberrations of mirrors and lenses,was be used in LAMOST to improve image quality. A quite bright star is required in the center of view field of the telescope when S-H method is used and it will bring the blind area if the brightness of the S-H star is limited. In this paper, the effect of S-H on sky tiling is analyzed and the completeness of tiling is calculated based on Tycho-2 star table. |
