Abstract

I present a new software tool, called "Interferometry Visibility Computations" (IVC), for sparse uv-coverage optical/IR interferometry. It is aimed to compute interferometric observables from a large grid of geometrical toy models, or user supplied multi-wavelength radiative transfer simulations. It is designed to prevent aliases at high spatial frequencies when computing visibilities from imaging models and to perform multi-baseline model fitting taking into consideration various instrumental effects. The program can be called from any user's code to allow simultaneous model fitting of different types of observations, in order to compare e.g. interferometric and spectroscopic observations at the same time.
