241. ADASS 2003 Conference Proceedings
... Gomez, J. C., Athanassoula, L., Fuentes, O., & Bosma, A. 2003, in ASP Conf. ... In this work we present Evolution Strategies (ES) as an efficient method to approximate the initial conditions of the main interacting group of three galaxies in M81. ... In this first attempt we use non-self-gravitating simulations to approximate the initial conditions; even with that restriction our method reproduces the density distribution of the three galaxies with great precision. ...

242. ADASS 2003 Conference Proceedings
... We present the first results of a system for automatic analysis of astronomical images from digitized plates. This system will automatically identify spectral lines in low resolution spectra employing image processing and analysis. ... This work is focused in the spectral plates only. ... Our objective is to develop an algorithm of optimal and robust segmentation of stellar spectra on spectral plate images with the purpose of identifying its spectral lines in an automatic form. ...

... Grumm, D. & Casertano, S. 2003, in ASP Conf. ... The actual on-orbit data will doubtless suffer from geometric distortion and cosmic rays at some level, while calibration is required to simultaneously derive the sky and flat field in the presence of these effects to a level of better than a part in 10,000. ... The original iterative self-calibration program has been described in the poster ``Self Calibration for the GOODS Legacy Project'' presented at ADASS 2002 (Grumm & Casertano 2003) . ...

... Rohlfs, R. 2003, in ASP Conf. ... With AstroROOT we can store astronomical data organized in tables and images in ROOT - files using the efficient I/O system of ROOT. ... In total ROOT is a C++ - library with more than 100 classes. ... Another advantage is the possibility to store astronomical data not only in FITS files but also in ROOT files, using the I/O system of ROOT. ... These are FITS file access in the ROOT interpreter and an astronomical image display within the ROOT framework. ...

... Starlink is extending ORAC-DR to process at home institutions data from other observatories, notably ESO, whose instruments make no provision for ORAC-DR. I outline the problems encountered and solutions implemented or proposed to apply ORAC-DR to the infra-red instruments ISAAC, NACO, INGRID, and Classic Cam. ... These comprise steering headers like the observation and group numbers, and recipe name; and recipe-specific metadata, such as filter, exposure time, and grating name. ...
