Next: Image Processing of Digitized Spectral Data . ... We have proposed the 2-CLEAN DSA (Determination of Solution Area) method for the estimation of the area of possible images (from the ``obtuse" (smooth) to the ``sharp" variants) in complicated cases with constraints and poor information. ... The method of 2-CLEAN DSA allowed us to determine that the area of the permissible solutions lies formally between the ``sharp" (CLEAN) and ``smooth" (TC-CLEAN) variants. ...

... Determination of the Permissible Solutions Area by Image Reconstruction from a few Projections: Method 2­CLEAN DSA Michail I. Agafonov Radiophysical Research Institute (NIRFI), 25 B.Pecherskaya st., Nizhny Novgorod, 603600, Russia, E­mail: agfn@nirfi.nnov.su Abstract. ... Application The problem requires the solution of the equation G = H # F (+noise) , (1) where F (x, y) is the object brightness distribution, H(x, y) is the fan (dirty) beam, and G(x, y) is the dirty (summary) image. ...

... The material in "From Stargazers to Starships" meets several important requirements of the national standards. Pages cited below are from National Science Education Standards National Academy Press, Washington 1995. ... For example: the sections on astronomy not only describe calendars and sundials (including their construction), but also the astronomy of the ancient Greeks, including two different ways in which ancient Greeks estimated the distance to the Moon. ...

Next: Reduction procedure Up: Extinction and transformation Previous: Strategy . Standard stars can be included in the extinction solution, if one is careful. The problem is that there are usually appreciable ``conformity errors'' due to mismatch between the instrumental and the standard passbands [ 16 ]. ... Thus, it is wrong to assume that the transformation between the instrumental system and the standard system is exact, even if there were no measurement error in either system [ 1 ]. ...
