... Now over a year since the first light image of Cas-A, Chandra has observed several hundred science targets and many calibration ob jects. A few highlights from these data are presented - including a discussion of the spatially resolved spectrum of supernova ejecta in Cas-A and X-ray emission from the central regions of M31, the nearby AGN Cen-A, and the quasar 3C273. ... The second panel in Figure 6 shows the radio emission at 6 cm plotted over the X-ray image along the jet. ...

... VSIPL and OpenMP are two open standards for portable high performance computing. ... Image processing is one of the main areas where VSIPL and OpenMP can have a large impact. Currently, a large fraction of image processing applications are written in the Interpreted Data Language (IDL) environment. The aim of this work is to demonstrate that the performance benefits of these new standards can be brought to image processing community in a high level manner that is transparent to users. ...

811. A New Field-Matching Method for Astronomical Images
... Previous: ATV: An Image-Display Tool for IDL . ... 238, Astronomical Data Analysis Software and Systems X, eds. F. R. Harnden, Jr., ... We propose a new Field-Matching algorithm for astronomical images. This new method is based on a multiresolution analysis. We tried two cases: first, we compared the test image with a synthetic image built from a point source catalog; second, we used a reference image of the relevant portion of the sky. ... Moreover, the new algorithm is faster than FOCAS. ...

812. Converting FITS into XML: Methods and Advantages
... Up: Software Applications . ... We discuss how and why FITS data should be encapsulated in XML. ... A probable path in this cycle could be: data are taken at the telescope as FITS, they are submitted to a publisher in L A T E X , the publisher converts these data into SGML, data centers convert the SGML into some form of ASCII (such as HTML), and the end-user downloads this and converts the data back into FITS (!) for use in various analysis software. ... XDF and FITSML are works in progress. ...

813. Uniform Data Sampling: Noise Reduction & Cosmic Rays
... The effects of radiation and cosmic rays can be a formidable source of data loss for a space-based observatory. ... We evaluate Up-the-Ramp sampling with on-the-fly cosmic ray identification and mitigation, which is described in detail by Fixsen et al. (2000) and compared to Fowler Sampling (Fowler & Gatley 1990). ... Furthermore, on-the-fly cosmic ray rejection allows longer integration times which also improves the signal-to-noise in the faint limit (Offenberg et al. ...

... Previous: The CAOS Application Builder . ... Most of the faults caused by the radiation environments in regions of space of interest to REE (Deep Space, Low Earth Orbit) are transient, single event effects. ... We discuss different software fault tolerance approaches such as replication, voting, and masking with a focus on algorithm-based fault-tolerance. ... The radiation environment causes faults at the hardware level; many of which become errors at the application or system level. ...
