181. RVSAO 2.0 - A Radial Velocity Package for IRAF
... RVSAO 2.0 is the latest release of a package for calculating apparent radial velocities of celestial objects from observed spectral shifts. ... XCSAO cross-correlates the Fourier transform of an object's spectrum against the transforms of a set of template spectra with known spectral shifts to obtain a velocity and error. ... Full documentation of this software, including numerous examples of its use, is on-line at http://tdc-www.harvard.edu/iraf/rvsao/ . ...

182. The Distributed Analysis System Hierarchy ( DASH ) for the SUBARU Telescope
... We are developing a data reduction and analysis system DASH (Distributed Analysis Software Hierarchy) for efficient data processing for the SUBARU telescope. ... Moreover, we introduced a data reduction procedure cube ( PROCube ) as a kind of visual procedure script. ... DASH is, therefore, designed as an observatory system for astronomical data reduction and analysis, which cooperates with the SUBARU observation software system and the data archival system. ... DASH aims at open architecture. ...

183. Recognition of Anomalous Events
... Previous: A Posteriori Guidance for Astronomical Images . ... We present an original algorithm for the recognition of anomalous events in a CCD frame (i.e., cosmic hits, bad pixels etc.) The algorithm is able to distinguish between these events and real features by comparing the standard deviation and the kurtosis of a synthetic PSF, whose width is given by the user, and the corresponding values in a running window, whose size is chosen by the user, in the actual frame. ...

186. A Multidimensional Binary Search Tree for Star Catalog Correlations
... A multi-dimensional binary search tree, k-d tree, is proposed to support range queries in multi-key data sets. The algorithm can been used to solve a near neighbors problem for objects in a 19 million entries star catalog, and can be used to locate radio sources in cluster candidates for the X-ray/SZ Hubble constant measurement technique. ... The choices for the problem at hand were narrowed down to two : a Multidimensional k-ary Search Tree (MKST) and a k-dimensional (k-d) tree. ...

189. Methodology of Time Delay Change Determination for Uneven Data Sets
... It was found in this way that the radio variations (5 MHz) followed the optical ones, but that the time delay was a linear function of time with the mean value being about 2370 days and with the rate of increase days/year. ... We take days/year as the test value. ... To show that the method has real abilities to determinate a value of of the time delay rate of increase in the light curves we again use Monte-Carlo simulation as it is explained in (1) and (2), but the actual value is 110 days/year. ...

194. 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. ...

195. 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. ...
