221. A Software Package for Automatic Reduction of ISOPHOT Calibration Data
... Also the measured signals are affected by detector transients, altering the final results considerably. We present the design and the main features of a software package, developed in order to support the absolute calibration of the instrument. ... In case the fit is not successful, the average of the last 30% of the data is taken as the final signal. ... The two different symbols represent individual calibrations of the final background signals, using the first or the second FCS-signal. ...

222. Determination of the Permissible Solutions Area by Image Reconstruction from a
Next: Image Processing of Digitized Spectral Data . ... We have proposed the 2-CLEAN DSA (Determination of Solution Area) method for the estimation of the area of possible images (from the ``obtuse" (smooth) to the ``sharp" variants) in complicated cases with constraints and poor information. ... The method of 2-CLEAN DSA allowed us to determine that the area of the permissible solutions lies formally between the ``sharp" (CLEAN) and ``smooth" (TC-CLEAN) variants. ...

226. How to Piece Together Diffracted Grating Arms for AXAF Flight Data
... The Advanced X-ray Astrophysics Facility's (AXAF) High and Low energy transmission gratings (HETG, LETG) data require new tools and data structures to support x-ray dispersive spectroscopy. ... The sky coordinates, which are referenced to the telescope mirror node and therefore independent of the grating reference node, are only useful for the imaging of zero order and the filtering of grating arm photons. ... For more details on the AXAF grating flight processing software, see: . ...

228. Astro-E's Mission Independent Scheduling Suite
... TAKO (``Timeline Assembler, Keyword Oriented'', or in Japanese, ``octopus'') is our in-progress suite of software that takes database input and produces mission timelines. ... The three main factors to consider are calculated quantities (i.e., unchangeable facts of the situation), derived quantities (soft constraints, ratings of good and bad events, and politics), and capacity constraints (such as time and telemetry). ... And, TAKO is modular by design, to allow for use with different missions. ...

233. VLT Data Quality Control
... As modern observatories evolve to production units delivering data products and calibrated scientific data to the end users, new challenges arise in assessing the quality of data products. ... Taking the analogy of speed control on a motorway we can describe the system as a device (radar) collecting measurements of the system performance (passing cars). ... One of the direct applications of quality control is the verification of instrument performance based on the analysis of calibration exposures. ...

235. Robust, Realtime Bandpass Removal for the HI Parkes All Sky Survey Project
... We present the algorithm and implementation details for the robust, realtime bandpass removal and calibration routine developed for the HI Parkes All Sky Survey project. ... Traditionally, the bandpass that is present in single-dish 21 cm spectra is removed by observing in a ``signal-reference'' mode. ... The robust bandpass removal algorithm implemented for the HIPASS Project successfully produces calibrated HI emission line spectra for most of the survey data. ...

... We have performed a series of tests to find an optimal data distribution in the Cray T3D memory, and to identify a strategy for the Dynamic Load Balance (DLB). ... N-body simulations are one of the most important tools in contemporary theoretical cosmology, however the number of particles required to reach a significant mass resolution is more larger than those allowed even by present-day state-of-the-art massively parallel (Gouhing 1995; Romeel 1997 & Salmon 1997) supercomputers (hereafter MPP). ...
