... Abstract: We present an extensive study of the radiative transfer in dusty galaxies based on Monte Carlo simulations. ... We have explored the dependence of A_l on a conspicuous set of quantities (Hubble type, inclination, dust optical thickness, dust distribution and extinction properties) for a large wavelength interval, ranging from 1250A to the K band, thus finally providing a comprehensive atlas of dust extinction in galaxies, which is electronically available. ...

Next: Model Spectra for Spectral-Fitting Up: Spectral Analysis Previous: A Quick Look at . ... For ROSAT PSPC data, this conversion is done during the on-line (SASS) processing. For IPC observations, the instrument gain varies both across the detector and in time, and is applied during off-line processing (PROS) using the BAL histogram. By default, spectra are extracted in PI bins for PSPC data and in PHA bins for IPC data. ... Special techniques are required when using Einstein IPC data. ...
Next: Access to Data Sources and the ESO SkyCat Tool . ... We describe an implementation of Dynamic Queries (DQ), a recently developed method as an alternative to the perceived complicated SQL-type operations on relational databases by a very intuitive graphical interface. This prototype implementation, written within the NEMO package, uses ASCII sliders and the PGPLOT graphics interface and uses a novel interactive analysis back-end tool that is dynamically associated with the query. ...
