- Description:
- The Hubble Ultra Deep Field 2009 (HUDF09) program observations were obtained as HST program 11563 (PI: Garth Illingworth) from August 2009 to February 2011 (Cycle 17). The program uses WFC3/IR as the prime instrument for 192 orbits to image the deep ACS fields that were obtained in the original HUDF (PI: Steven Beckwith) program and in the HUDF05 (PI: Massimo Stiavelli) program. The data are organized into sets of images by HUDF09 pointing and by passband (WFC3/IR F105W, F125W & F160W). Each image is approximately 3k x 3k pixels in size and a scale of 0.06 arcsec/pixel. All three pointings reside in the GOODS/Chandra South field and each pointing includes a drizzled science image and a weight image.

- Publisher:
- NASA/IPAC Infrared Science Archive
- Description:
- This new generation of IRAS images, called IRIS, benefits from better zodiacal light subtraction, calibration and zero levels compatible with DIRBE, and better destriping. At 100 microns, the IRIS product is also a significant improvement over the Schlegel et al. (1998) maps. IRIS keeps the full ISSA resolution, includes well calibrated point sources, and the diffuse emission calibration at scales smaller than 1 degree was corrected for the variation of the IRAS detector responsivity with scale and brightness. The uncertainty on the IRIS calibration and zero levels is dominated by the uncertainty of the DIRBE calibration and the accuracy of the zodiacal light model.

- Description:
- The IRIS data is a reprocessing of the IRAS data set and has the same geometry as the IRAS Sky Survey Atlas (ISSA, labeled as IRAS nnn micron in <i>SkyView</i>) surveys. This new generation of IRAS images, called IRIS, benefits from a better zodiacal light subtraction, from a calibration and zero level compatible with DIRBE, and from a better destriping. At 100 micron the IRIS product is also a significant improvement from the Schlegel et al. (1998) maps. IRIS keeps the full ISSA resolution, it includes well calibrated point sources and the diffuse emission calibration at scales smaller than 1 degree was corrected for the variation of the IRAS detector responsivity with scale and brightness. The uncertainty on the IRIS calibration and zero level are dominated by the uncertainty on the DIRBE calibration and on the accuracy of the zodiacal light model. <p> More information about the IRIS dataset is available at <a href="https://www.cita.utoronto.ca/~mamd/IRIS"> the IRIS website</a> whence most of the preceding description came.

- Description:
- INAF-OATs SVAS Educational Images SIAP service. Le Stelle Vanno A Scuola (SVAS) proposes a modern tool to support teaching of astronomy, through the study and experimentation of its observation methods. SVAS offers to schools and teachers a remote laboratory with which carry out real observation sessions, managed in real time by the students under the supervision of the teacher, in the classroom, and of an astronomer, at the OATs, thanks to the telematic link between the school and the observatory. Students and teachers experience real astronomical observations, through the interactive participation to the different steps of planning, observing and acquiring the data. The project is addressed to 13-18 yr students. Every observation is previously planned together with the teachers, according to age and curriculum of the students, with the aim to maximize the results. The observing activity, lasting about 90 minutes and led by an astronomer of the OATs, can be done during the morning (observation of the Sun) or in the evening (observation of stars, nebulae, clusters and galaxies). SVAS involves the Astronomical Observatory of Trieste (OATs), the school (of every level) and the University of Trieste. SVAS is supported by the Consorzio per l’Incremento degli Studi e delle Ricerche dei Dipartimenti di Fisica e Astronomia dell’Università di Trieste and by the Ministero dell'Istruzione, dell'Università e della Ricerca.

- European Space Agency
- Description:
- The Infrared Space Observatory (ISO) was the world's first true orbiting infrared observatory. Equipped with four highly-sophisticated and versatile scientific instruments, it was launched by Ariane in November 1995 and provided astronomers world-wide with a facility of unprecedented sensitivity and capabilities for a detailed exploration of the Universe at infrared wavelengths. The two spectrometers (SWS and LWS), a camera (ISOCAM) and an imaging photo-polarimeter (ISOPHOT) jointly covered wavelengths from 2.5 to around 240 microns with spatial resolutions ranging from 1.5 arcseconds (at the shortest wavelengths) to 90 arcseconds (at the longer wavelengths). Its 60 cm diameter telescope was cooled by superfluid liquid helium to temperatures of 2-4 K.

- Description:
- The INTEGRAL observatory (Winkler et al. 2003, A&A, 411, L1) was launched in October 2002. The spectrograph SPI (Vedrenne et al. 2003, A&A, 411, L63) consists of 19 Germanium detectors and is capable of imaging in the 20 - 8000 keV band because of a coded mask. Part of the core program of the INTEGRAL mission is a study of the Galactic Centre, the Galactic Centre Deep Exposure (GCDE).<p> The SPI significance map is based on the public GCDE data and uses data in the 20 - 40 keV energy range. The analysis of the data was done using the SPIROS software (Skinner & Connell 2003, A&A, 411, L123). This software uses the 'Iterative Removal of Sources' technique in order to find the most significant sources. In the output significance map the sources found in this process are put on top of the residual map as points with a FWHM of 1 degree. <p> Current data respresent the combination of all public observations as of September 1, 2004. Provenance: INTEGRAL Science Data Center, Geneva, Switzerland. This is a service of NASA HEASARC.

- Description:
- The IRAC Ultradeep Field (IUDF) combines all ultradeep data ever taken with the Spitzer Infrared Array Camera (IRAC) at 3.6 and 4.5 microns over GOODS-South and the HUDF (+ parallels). The deepest observations come from the IRAC Ultra Deep Field (IUDF, ID 70145, PI Labbe) and IRAC Legacy over GOODS (IGOODS, PID 10076, PI Oesch) programs, combined with archival data from GOODS (PID 194, PI Dickinson), SEDS (PID 60022, PI G. Fazio), S-CANDELS (PID 70204, PI Fazio), ERS (PID 80217, PI Fazio), and UDF2 (PID 30866, PI Bouwens). The combined IRAC images in this data release amount to 1500 hour total integration time, ranging from >50 hour over 150 sq. arcmin, and >100 hour over 60 sq. arcmin, to ~200 hour over 5 - 10 sq. arcmin.
