This is slide 15 of 20 from the first Giotto slide set. The following caption is the one originally provided with the slide set. Throughout the mission the spacecraft attitude defined by the Sun aspect angle (0° -Sun above the tripod) must be kept inside an allowed corridor (light yellow) which is given by two constraints: The high gain antenna must permanently point at the Earth to maintain the telecommunications link (communications constraint, green line), and, secondly, the spacecraft must generate enough power without being heated up too much (thermal/power constraint, red line).
