Measurement of line profiles

Modelling of Nebular Line Profiles

RESUMEN El resumen será traducido al español por los editores. We present a tool, VELNEB 3D, which can be applied to the results of 3D photoionization codes to generate emission line profiles, position-velocity maps and 3D maps in any emission line by assuming an arbitrary velocity field. We give a few examples, based on our pseudo-3D photoionization code NEBU 3D (Morisset, Stasi´nska & Peña 20...

Fourier Transform Infrared Spectroscopy for the Measurement of Spectral Line Profiles

New Measurement Techniques for the on Line Dimension Characterization of Automotive Rubber Profiles

A vision-based measurement system for the online inspection of automotive rubber profiles is described. The system determines a 3-D reconstruction of the rubber profile section and performs dimensional measurements. After a brief description of the whole measurement system, the main novelties are pointed out: the simple calibration procedure and the flexible tools allowing users to specify the ...

Molecular Line Profiles of Collapsing Gas Clouds

Emission line profiles of tracer molecule H2CO 140 GHz transition from gravitational core collapsing clouds in the dynamic process of forming protostars are calculated, using a simple ray-tracing radiative transfer model. Three self-similar dynamic insideout core collapse models – the conventional polytropic model, the empirical hybrid model and the isothermal model – for star-forming molecular...
