Several region shapes can be selected through parameter shape : circle, box, diamond, ellipse and boxcircle. The size of these regions is determined once the radii is calculated as explained in previous section: . - box side = circle_radius . - ellipse_minor_axis= circle_radius . - ellipse_major_axis= circle_radius .

The information path to prepare, perform and reduce a radioastronomical observation, using the Arcos correlator , is schematized in the figure: . The programs reside part on the computer network of the Arcetri Observatory, and part at the Medicina Radio Telescope . All programs running at Arcetri are written for a Sun workstation, and are public domain software, available upon request. Programs running at the telescope are written for a PC with DOS/Windows (or Linux).
