Spitzer Heritage Archive Demo

| Trey Roby | Caltech / IPAC |
| Spitzer Heritage Archive will be released to the public in January 2010. This AJAX-based web application requires no plug-ins but contains advanced web technologies such as a true FITS viewing, interactive tables, field validation, and many other features that have historically only been available as a desktop application. Watching the demo makes it easy to forget that we are using a web browser! It also compliments two invited talks ″Archive Web sites using AJAX & GWT″ (given by Trey Roby) and ″Spitzer Heritage Archive″ (given by Xiuqin Wu). The heritage archive system will initially contain the raw and final reprocessed cryogenic science products, and will eventually incorporate the final data products from the Spitzer Warm Mission. It has been designed and developed under collaboration of Spitzer Science Center(SSC) and NASA/IPAC InfraRed Science Archive (IRSA). It took advantage of the SSC and IRSA existing technology and knowledge base. In August 2003, NASA launched Spitzer. During its mission, Spitzer obtained images and spectra by observing between wavelengths of 3 and 180 microns with three instruments: IRAC, IRS, and MIPS. Its cryo mission ended May 2009. \Spitzer is now in the warm mission, observing in 3.6 and 4.5 microns using IRAC instrument. | |

| Jonathan E Fay | Microsoft Research |
| WorldWide Telescope is a non-commercial project from Microsoft Research designed to provide application, services, tools and data to astronomy researchers, educators and the public. WorldWide Telescope provides rich visualization of Multispectral Deep Sky Data, Planetary data including the Earth, and 3d data visualization of parallax, red-shift and simulation data. | |

| YOUPI Pipeline | |
| Mathias Monnerville | Terapix, Institut d'Astrophysique de Paris, UPMC, CNRS |
| Youpi stands for ″YOUpi is your processing PIpeline″. It is a modern, easy to use yet powerful web application providing high level functionality to perform data reduction on FITS images. Built on top of various open source reduction tools released to the community by TERAPIX, Youpi can organize your data, manage your processing jobs on a cluster in real time (using Condor) and facilitate teamwork by sharing results and data between users. Built from the ground up with modularity in mind, Youpi comes with plugins allowing to perform, from within a browser, various processing tasks such as evaluating the quality of incoming images (using the QualityFITS software package), computing astrometric and photometric solutions (using SCAMP), resampling and co-adding FITS images (using SWarp) and extracting sources and building source catalogues from astronomical images (using SExtractor). Whether you are dealing with small to medium-sized data reduction projects, Youpi can be a powerful alternative to other pipeline data reduction software. Youpi is free software and is released under the GNU General Public License. | |

| Modular Pipelines and Scientific Workflows at ESO | |
| Klaus Banse | ESO |
| CPL based pipelines for the VLT instruments on Paranal are in operational use since many years at ESO. Currently, we′re working on an infrastructure enabling the observers to rerun the data reductions which were performed during pipeline processing. Therefore, the complex pipeline recipes are split up into smaller, meaningful modules which are executable within our graphical, scientific workflow system, ESO-Reflex. In Reflex these modules can then be chained together to execute the same overall pipeline reduction as the original recipe, but with the possibility of fine tuning the parameters for the different subrecipes, repeating a given sequence of recipes, or interrupting the pipeline at any time to inspect intermediate results. We′ll demonstrate ESO′s work in progress on the workflow system using the HAWK-I pipeline. | |

| Building Astronomical Databases with Saada PDF | |
| Laurent MICHEL | Universite de Strasbourg |
| A lot of astronomers would like to share datasets with the community but have no manpower to develop databases providing functionalities with high scientific level. The Saada project aims at helping them by automatically generating from data files databases (SaadaDBs) located on any local computer. SaadaDBs can simultaneously host heterogeneous sets of spectra, images, source lists or any other files. Data stored in SaadaDBs can be correlated each to others with qualified links helping for example for cross-identifications or for modeling some other scientific content. The query engine is based on a specific language (SaadaQL) fitting well the data model. In addition with classical astronomical queries, it can process constraints on correlated data. Databases created by SAADA can be accessed by a WEB interface allowing data browsing or data selection with complex queries. They also implements VO protocols and data models providing then a solution to publish local data into the VO. | |

| Chandra Source Catalog Data Access and Analysis | |
| Mark L. Cresitello-Dittmar | Smithsonian Astrophysical Observatory, CXC |
| The initial release of the Chandra Source Catalog (CSC) was published in March 2009, and includes information for approximately 95,000 point and compact X-Ray sources. These sources were detected from a subset of public ACIS imaging observations taken during the first eight years of the Chandra mission. The CSC entries contain statistical characteristics of commonly tabulated quantities, including source position, extent, multi-band fluxes, hardness ratios, and variability statistics. In addition, the CSC includes an extensive set of file-based data products including source images, event lists, light curves, and spectra.To access and analyze this catalog, the Chandra X-ray Center (CXC) offers numerous interfaces along with our standard data analysis package CIAO. The first set of new tools used in the Catalog Processing pipeline have been released in CIAO 4.1.2. We plan to demonstrate these public interfaces and analysis tools available to Chandra users and highlight some of the new applications. The demos include: CSCView, a Java GUI to the catalog which provides access to Chandra data for sources matching user-specified search criteria; DS9 Catalog tool interface to access and display data from the catalog; A registered IVOA Simple Cone Search service which enables VO-aware applications such as DataScope, TOPCAT, and WWT to retrieve tabulated CSC source data; Google Earth, an interface for visualizing Field-of-Views, images and obtaining summary source information; and new CIAO tools including srcextent and modelflux, which use our fitting application Sherpa to calculate source properties. | |
