1664. Querying by Example Astronomical Archives
... In this paper, a project aiming to allow access to data archives by means of a query-by-example mechanism is described. The basic user query would simply be the submission of an input image, either 1-D or 2-D; the system should allow retrieval of archived images similar to an input one on the basis of some ``resemblance parameter". ... A system called QUBE is currently being designed to support the QUery-By-Example paradigm in accessing astronomical data archives. ... the QUBE User Interface. ...

1665. Integrating the ZGSC and PPM at the Galileo Telescope for On-line Control of
... The usage of catalogs is extremely important for efficiently observing with up-to-date instrumentation. In the work described in this paper, GSC sources are cross-correlated with entries in the PPM catalog, and used as an input to the control software of the Galileo Telescope (TNG). ... Maintaining the catalog on-line requires either two dedicated CD-ROM drives (or a jukebox), or over 1GB of hard disk space. ... We have created a compressed version of the GSC, called ZGSC (Smirnov & Malkov 1997a). ...

... This paper describes recent improvements to the FITSIO subroutine library and the fv FITS file viewer and editor, both of which were initially described at previous ADASS conferences. ... Since the time of the last FITSIO update (Pence 1995) a new CFITSIO library has been developed, written entirely in C. CFITSIO is easier for C programmers to build and call than the previously available C wrapper routines built on top of the FORTRAN FITSIO library. ...

1671. Slitless Multiobject Spectroscopy with FOSC Type Instruments
... We present a simple, effective technique that allows the contemporary spectroscopy of all the objects, up to a limiting magnitude, contained in a 100 arcmin 2 field. ... For this reason, we have developed a technique, that allows the simultaneous spectroscopy of all the objects included in a square field of view with 10 side, using the widely used FOSC-type optical spectrometer and camera focal-plane instruments. ... Thus the flux calibration of the slitless spectra was also straightforward. ...

1672. A Queriable Repository for HST Telemetry Data, a Case Study in using Data
... The Hubble Space Telescope (HST) generates on the order of 7,000 telemetry values, many of which are sampled at 1Hz, and with several hundred parameters being sampled at 40Hz. ... As part of the recent NASA initiative to re-engineer HST's ground control systems, a concept arose to apply newly available data warehousing technologies to this problem. ... In addition to routine study and problem analysis, we use telemetry to look for long term trends in how the platform is behaving. ...

1674. Positive Iterative Deconvolution in Comparison to Richardson-Lucy Like
... Positive iterative deconvolution is an algorithm that applies non-linear constraints, conserves energy, and delivers stable results at high noise-levels. This is also true for Richardson-Lucy like algorithms which follow a statistical approach to the deconvolution problem. ... All algorithms resolve the objects, as shown by the reconstructions by Richardson-Lucy in Figure 2 on the right, the algorithm by M?ller in Figure 3 on the left and positive iterative deconvolution in Figure 3 on the right. ...

1676. OPUS-97: A Generalized Operational Pipeline System
... OPUS is the platform on which the telemetry pipeline at the Hubble Space Telescope Science Institute is running currently. ... The OPUS platform handles communication with the OPUS blackboard; individual processes within this pipeline need have no knowledge of OPUS, of the blackboard, or of the pipeline itself. The OPUS API is an intermediate pipeline product. ... Where the OPUS platform is a generalized pipeline environment, it does not provide the applications which handle mission-specific data. ...
