... 295, 2003 H. E. Payne, R. I. Jedrzejewski, and R. N. Hook, eds. A New Way of Joining Source Catalogs using a Relational Database Management System Clive G. Page AstroGrid Project, Department of Physics & Astronomy, University of Leicester, U.K. Abstract. New science often arises from joining source catalogs obtained from different wavebands, but efficient methods for performing such joins depend on multi-dimensional indexing and are poorly handled by most DBMS. ...

... The scientific value of the internal indexation files is much higher though, as they keep track of the source density of catalogues and hence allow us to answer a family of questions not easily handled by a standard DB system and providing an unusual visual aid: a snapshot of the location of sources listed in any catalog. ... Another important issue of today's data is to describe the sky coverage of a catalogue and use that information to speed up the cross correlation process. ...

... Intelligent agents carry out resource discovery, submit observing requests, and analyse the reduced data returned by the telescope nodes. The agents are capable of carrying out data mining and cross-correlation tasks using online catalogues and databases and, if necessary, requesting follow-up observations from the telescope nodes. ... The design is analogous to computational grids, with no overall supervisor, giving the system scalability with multiple agents talking to multiple nodes. ...

We then discuss two of the algorithms used in the SDSS image processing, the KL-transform based modelling of the spatial variation of the PSF, and the use of galaxy models in star/galaxy separation. ... Application to SDSS data: For each CCD, in each band, there are typically 15ґ25 stars in a frame that we can use to determine the PSF; we usually take n = 3 and N = 2 (i.e., the PSF spatial variation is quadratic). ...

678. New Elements of Sherpa, CIAO's Modeling and Fitting Tool
... We describe enhancements made to Sherpa for the CIAO 2.0 release, concentrating upon those that enable a user to: (1) analyze Chandra X-ray Observatory grating data with wavelength- or energy-space models; (2) simultaneously fit background and source datasets; and (3) estimate and visualize confidence intervals and regions. ... Sherpa is the modeling and fitting tool of the Chandra Interactive Analysis of Observations (CIAO) software package (Doe et al. 1998 and references therein). ...
