Download or read book The AFGL Four Color Infrared Sky Survey written by Stephan D. Price and published by . This book was released on 1977 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Positions and magnitude measurements at effective wavelengths of 4.2, 11.0, 19.8, and 27.4 micrometers are reported for an additional 2477 sources observed during the AFGL survey program. These sources were obtained by relaxing the stringent selection criteria used for the main catalog and subjectively selecting those that have associations and/or other characteristics which make them of interest for future investigation.

Book Synopsis Aspect Determination for the AFGL Infrared Survey Experiments by : Stephan D. Price
Download or read book Aspect Determination for the AFGL Infrared Survey Experiments written by Stephan D. Price and published by . This book was released on 1978 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The AFGL probe borne infrared celestial survey experiments are designed to obtain the inertial aspect of the payload reference frame with an accuracly comparable to the spatial size of a resolution element in the infrared telescope. Constraining the axis of payload rotation to known inertial coordinates through maintaining lock onto a selected pole star with a star tracker co-aligned to the roll-axis, and by careful geometric alignment of the optical elements and dynamic balancing the payload, the desired accuracy was achieved. Further refinement in position was obtained from the stellar detections by the infrared sensor, with an ultimate knowledge of the inertial aspect being within 1.5 artc minutes root mean square deviation between the measured and catalogued positions for known infrared stars. The procedures used to obtain this accuracy are described. Also detailed is a method of aspect determination using only a star mapper with an N slit focal plane reticle. (Author).
Book Synopsis An Infrared Survey of the Diffuse Emission Within 5° of the Galactic Plane by : Stephan D. Price
Download or read book An Infrared Survey of the Diffuse Emission Within 5° of the Galactic Plane written by Stephan D. Price and published by . This book was released on 1980 with total page 174 pages. Available in PDF, EPUB and Kindle. Book excerpt: The AFGL Infrared Sky Survey data have been processed to deconvolve the low frequency attenuation, restoring the signals from extended sources. The 11 and 20-micrometer scans which cover three quarters of the galactic plane have been analyzed, with lesser area covered at 4 and 27 micrometers. A detailed description is given of the instrumentation, the conduct of the experiment, and the data reduction procedures. The measured extended emission in the 3- to 30-micrometer region may be divided into several components. A number of discrete, extended sources are observed within 5 deg of the galactic plane, the majority of which are associated with HII regions. About 25 percent of these sources are not in the AFGL catalog. A large scale diffuse emission is centered on the galactic plane at longitudes less than 90 deg from the galactic center. The 11 to 20-micrometer color ratio of this emission is distinctly smaller in the direction of the Perseus external arm and the Sagittarius-Carina spiral than closer to the center (1

Book Synopsis The Impact of Large Scale Near-IR Sky Surveys by : F. Garzón
Download or read book The Impact of Large Scale Near-IR Sky Surveys written by F. Garzón and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: After a year's successful operation, the European DENIS project is now a scientific reality and its close cousin 2MASS (USA) is about to come into operation. The observational and data reduction processes of both DENIS and 2MASS are fully described in this volume. Already the impact of DENIS is making itself felt in the astronomical community in areas of research as diverse as cosmology, the evolution of galaxies, the interstellar medium, the search for brown dwarfs, and stellar structure and evolution. The first routine results from DENIS and the preliminary results from the 2MASS prototype camera are discussed and compared with other surveys across the wavelength spectrum, both space- and ground-based, including the Digitized Sky Survey, ISO and ROSAT.

Book Synopsis Inventing a Space Mission by : Vincent Minier
Download or read book Inventing a Space Mission written by Vincent Minier and published by Springer. This book was released on 2017-11-26 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes prominent technological achievements within a very successful space science mission: the Herschel space observatory. Focusing on the various processes of innovation it offers an analysis and discussion of the social, technological and scientific context of the mission that paved the way to its development. It addresses the key question raised by these processes in our modern society, i.e.: how knowledge management of innovation set the conditions for inventing the future? In that respect the book is based on a transdisciplinary analysis of the programmatic complexity of Herschel, with inputs from space scientists, managers, philosophers, and engineers. This book is addressed to decision makers, not only in space science, but also in other industries and sciences using or building large machines. It is also addressed to space engineers and scientists as well as students in science and management.
