Book excerpt: A survey of the sky in the intermediate infrared spectral region is reported. The objective was to obtain the brightness and spatial distribution of a representative sample of the types of celestial objects that emit strongly in the infrared. Of primary concern was the determination of the positions of unusual sources of emission with sufficient accuracy to enable them to be acquired by ground based telescopes for further detailed investigation.

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.

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

Download or read book The Far Infrared Sky Survey Experiment Final Report written by Stephan D. Price and published by . This book was released on 1983 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Approximately 9000 square degrees of the celestial sphere was surveyed in four infrared bands with a rocket-probe-borne telescope. This Far Infrared Sky Survey Experiment (FIRSSE) covered the galactic plane between 120 degrees and 255 degrees longitude and the Orion and Taurus Molecular Clouds. A list of almost 300 bright 90 μm sources is presented along with associated measurements at 20, 27, and 40 μm. A description is given of the conduct of the experiment, the first space-borne use of super-fluid helium under active thermal loading.

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).
