Proceedings ArticleDOI
Determination of Spitzer Space Telescope focus from IRAC images without a focus slew
William F. Hoffmann,Joseph L. Hora,John Eric Mentzell,Catherine T. Marx,Peter Eisenhardt,Sean Carey,S. T. Megeath,John P. Schwenker +7 more
TL;DR: In this paper, the authors used Simfit and focus diversity to determine the focus of the Spitzer Space Telescope (SST) secondary focus mechanism, which brought the focus close to the specified requirement of within 0.3 mm from the desired IRAC optimum focus.
Proceedings ArticleDOI
Simfit and Focus Diversity: methods for determining the focus of the SIRTF telescope in space without a focus slew
TL;DR: In this paper, Simfit and Focus Diversity are used to compare an observed stellar image with a family of simulated point-source images with a range of focus settings, and the focus offset and direction can be accurately and unambiguously determined.
Proceedings ArticleDOI
Wide-Field InfraRed Survey Telescope (WFIRST) slitless spectrometer: design, prototype, and results
Qian Gong,Margaret Z. Dominguez,Thomas J. Emmett,Ulf Griesmann,John G. Hagopian,Jeffrey W. Kruk,Catherine T. Marx,Bert A. Pasquale,Thomas Wallace,Arthur Whipple +9 more
TL;DR: In this article, the progress of the compound grism prototype is discussed, including the fabrication and test of the complicated diffractive optical elements and powered prism, as well as grism assembly alignment and testing.
Proceedings ArticleDOI
Design and performance of a high-throughput cryogenic detector system
Elmer Sharp,Dominic J. Benford,Dale J. Fixsen,Stephen F. Maher,Catherine T. Marx,Johannes Staguhn,Edward J. Wollack +6 more
TL;DR: The Goddard IRAM Superconducting Millimeter Observer (GISMO) is a new superconducting bolometer array camera for the IRAM 30 Meter Telescope on Pico Veleta, Spain this article.
Proceedings ArticleDOI
