a photographic technique for clarifying the telescopic images of a star by taking short exposures of the electronic images of the star’s speckle pattern and extrapolating properties of the starlight to create a more accurate composite image.
(astronomy) a technique to increase the angular resolution of telescopes that are impaired by atmospheric turbulence, in which the information from a number of exposures of very short duration is combined
noun, Astronomy. 1. the visual appearance of a star as viewed through a large telescope, with irregularities caused by the distorting effect of local turbulence in the earth’s atmosphere.
benchmark The average of a set of floating-point and integer SPEC benchmark results. While the old average SPECmark89 has been popular with the industry and the press, SPEC has intentionally *not* defined an average “SPECmark92” over all CPU benchmarks of the 1992 suites (CINT92 and CFP92), for the following reasons: With 6 integer (CINT92) and […]
benchmark An old SPECmark benchmark result derived from a set of floating-point and integer benchmarks. It is the geometric mean of ten SPEC ratios of the outdated 1989 SPEC benchmark suite. The use of SPECmark89 is strongly discouraged, having been superseded by CINT92 and CFP92. (1994-11-29)
