A method has been developed to assess quantitatively science-performance criteria for the Large Space Telescope (LST) and to determine sensitivities to key design parameters for selecting design requirements that maximize performance and provide design margins within cost goals. The chosen performance measures relate to the quality and quantity of the scientific data and include measures of faint object and spectral sensitivity as well as spatial resolution. Computerized mathematical models of the LST's optical system were used to evaluate these measures as functions of three key LST design parameters: pointing instability, optical wave-front error, and aperture size. Parametric data are presented for the performance measures, and comparisons are made among telescope systems with various aperture sizes and systems with both analog and digital detectors.
