This chapter discusses various issues to do with the pointing, beam profiles and the effect they have on the photometric and wavelength calibration. It is an abridged version of Salama et al. 2001, [33], which should be consulted for more details of the observations, models etc.
Section 8.2 describes the SWS apertures. Section 8.3 introduces the focal plane geometry and Section 8.4 discusses the beam profiles of the various SWS aperture and detector combinations. Section 8.5 presents straylight suppression and Section 8.6 discusses satellite pointing.
