Query: APSYNSIM: An Interactive Tool To Learn Interferometry   The APerture SYNthesis SIMulator is a simple interactive tool to help the
students visualize and understand the basics of the Aperture Synthesis
technique, applied to astronomical interferometers. The users can load many
different interferometers and source models (and also create their own), change
the observing parameters (e.g., source coordinates, observing wavelength,
antenna location, integration time, etc.), and even deconvolve the
interferometric images and corrupt the data with gain errors (amplitude and
phase). The program is fully interactive and all the figures are updated in
real time. APSYNSIM has already been used in several interferometry schools and
has got very positive feedback from the students.
