Download or read book Revised Listing - S201 Far-Ultraviolet Atlas of the Large Magellanic Cloud written by Thornton T. Page and published by . This book was released on 1981 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: Far-ultraviolet electrographic images, covering the wavelength ranges 1050 to 1600 angstroms and 1230 to 1600 angstroms, were obtained of the Large Magellanic Cloud during the Apollo 16 mission with the NRL Far-Ultraviolet Camera/Spectrograph (Experiment S201). The images were analyzed as described in the 'S201 Far-Ultraviolet Atlas of the Large Magellanic Cloud' (NRL Report 8206), and the 'Revised S201 Catalog of Far-Ultraviolet Objects' (NRL Report 8487). The listing of far-UV objects in the LMC provided here is improved in quantitative accuracy and completeness compared to that originally provided in NRL Report 8206. These improvements include more accurate estimates of interstellar extinction corrections, comparisons with more sensitive ground-based H alpha emission measurements, and calibration of the S201 photometry by comparison with OAO-2 photometry of objects in common. The listing presents ultraviolet brightnesses, measured on one or more of four frames (two 1050 - 1600 angstroms and two 1250 - 1600 angstroms exposures), for 473 objects or gruopings of objects in the LMC. Also listed, where available, are H alpha brightnesses of associated nebulosities, and values of hydrogen index (defined as ratio of H alpha brightness to far-UV brightness, both corrected for interstellar extinction).

Download or read book S201 Catalog of Far-ultraviolet Objects written by Thornton Page and published by . This book was released on 1978 with total page 176 pages. Available in PDF, EPUB and Kindle. Book excerpt: A catalog of star images was compiled from images obtained by an NRL Far-Ultraviolet Camera/Spectrograph (Experiment S201) operated from 21 to 33 April 1972 on the lunar surface during the Apollo-16 mission. These images were scanned on a microdensitometer, and the output recorded on magnetic tapes. A set of seven computer programs were written to process these recorded outputs in order to compile the catalog. The catalog is divided into 11 parts, covering ten fields in the sky (the Sagittarius field being covered by two parts), and each part is headed by a constellation name and the field center coordinates. The errors in position of the detected images are less than about 3 arc-min. Correlations are given with star numbers in the Smithsonian Astrophysical Observatory catalog. Values are given of the peak density and the density volume (a product of the number of pixels in the image and the density units above background in each pixel). The text includes a discussion of the photometry, corrections thereto due to threshold and saturation effects, and its comparison with theoretical expectation, stellar model atmospheres, and a generalized far-ultraviolet interstellar extinction law. The S201 catalog is also available on a single reel of seven-track magnetic tape. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Reviews Apollo mission reports, preliminary science reports, technical crew debriefings, lunar surface operations plans, and various relevant lunar experiment documents, collecting engineering- and operation-specific information by experiment.
