Fig. 11.


Beam pattern (left), S/N (middle), and FFT (right) of the gridded visibilities of model 39 at a frequency of 690 GHz, rotated by 90 degrees on the sky and observed for 24 months with a 4.4 m reflector. Upper panels: simulations in case of polar satellite orbits, and lower panels: equatorial satellite orbits, taking the declination of Sgr A* (−29°) into account.
