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.
