From page 315...
... Astronomical use of these large facilities may be expanded by providing funds to support problem definition and software development and testing with university computers or dedicated minicomputers (as above) and by encouraging the large centers to make more time available for production runs.
From page 316...
... m e Space Telescope Wide-Field/Planetary Camera will produce typically fifty 1600 x 1600 images per day. The high spatial resolution afforded by this space observatory should, by mid-decade, provide astronomers with an unprecedented view of the deep reaches of the Universe.
From page 317...
... While we can easily predict an explosion in the number of digital images generated on the ground and in spacebased experiments, there appear at present to be few facilities capable of permitting individual astronomers to interact creatively with these data. If we are to take advantage of the promise of new imaging technology, it is crucial that the astronomical community, in conjunction with federal funding agencies, plan to develop and disseminate adequate image data-analysis capability throughout the United States.
From page 318...
... In the case of intensified arrays, geometrical corrections to remove the effects of image distortion introduced by the intensifier may also have to be applied. Radio maps must be explicitly corrected for sidelobe and other distortion effects, to provide appropriate intensity versus position maps at each observed frequency.
From page 319...
... The best scientific results derive from the active participation in data analysis by research astronomers and their graduate students operating on their own schedules with time to think about the intermediate results as they are obtained. For some problems, many man-months or -years are required in order to develop appropriate reduction algorithms.
From page 320...
... This basic difference in the required user response time of the facility serves to set the scale and nature of the equipment required. National Centers require integrated computer systems that allow efficient interleaving of batch and interactive processing in large volumes.
From page 321...
... Up to now the discussion in this section has concentrated on the hardware facilities required to provide adequate image processing and analysis capabilities. Of course, a substantial effort must be devoted to software development.
From page 322...
... The communications links will be used primarily for distribution of software updates and documentation. While such a system has advantages and is well matched to the needs of the British astronomical community, we believe that the Starlink model is not entirely appropriate for image processing and analysis in the United States.
From page 323...
... The National Centers (particularly Kitt Peak National Observatory, the National Radio Astronomy Observatory, and STScI) should take an active role in software development by 1.
