Exercise #2 Observability and UV coverage

D. Ségransan

Observatoire de Genève, 51 chemin des Maillettes, 1290 Sauverny, Switzerland


Abstract
This exercize is divided into two main parts. The first one intends to give a clear idea about the UV coverage with baselines of different orientations and targets of different declinations. It also emphasizes on the delay lines constraints for a 2 and a 3-telescope array. In the second part, different array configurations have to be selected to efficiently measure the radius of 3 close M dwarfs and the parameters ( $\rho$, $\Theta$, $\Delta$mag) of a binary system.
