... Despite the wide spread use of the terms MTF, CTF, limiting resolution, minimum resolvable target, and contrast to describe CCD image system quality, the terms are often misused and their relations are little understood. ... The modulation transfer function (MTF) is a Fourier transform of the line spread function i.e. its equivalent as an integral sum of sine waves taken over the whole range of spatial frequencies. MTF by its Fourier nature can only be used to operate on sinusoidal frequencies. ...

... RAPTOR Project , LANL Explanation: On December 11 astronomers found one of the brightest and most distant explosions in the Universe - a gamma-ray burst - hiding in the glare of a relatively nearby star.

... Meta Index / Home Page / Description / Spatial region settings A spectrum may be produced by filtering events using a 2-dimensional mask in either sky or detector coordinates. ... Preferable is a detector pixel image which just encompasses the masked region, otherwise a flat detector map will be ok. e.g. arfgen spectrumset=spectrum.ds extendedsource=yes detxbins=400 detybins=400 . ... The chip gap and bad pixel/column corrections will be correctly calculated if the detector map is fine enough. ...

... The remote planet Pluto and its moon Charon orbit the Sun at a mean distance of almost 6,000 million kilometres, or nearly fourty times farther out than the Earth. During a recent investigation by an international group of astronomers [1], the best picture ever of Pluto and Charon [2] was secured with the European Space Agency's Faint Object Camera at the Hubble Space Telescope (HST). ... The new HST image was taken when Charon was near its maximum elongation from Pluto (0.9 arcseconds). ...
