Abstract

The following exercices are aimed to get trained to the link between the object intensity distribution and the corresponding visibility curves. They were intended to be the practical application of the seminar "Introduction to visibility modeling" (Berger same volume). This practical session was initially meant to be done with the ASPRO software (see Duvert same volume), uv tables and the fits file can be donwloaded from the ASPRO website. However, any image processing or mathematical software (Idl, Yorick, Mathlab, Mathematica...) associated with the object equations given in Berger can be used for most exercises.
