focal_surface_parameters

Telescope: SSTS-design

Description: Defines the position of the focal surface along the optical axis and its off-axis shape. The par:focus-offset still applies, but with a curved focal surface only in the camera centre, such that star light would be focused on the camera lid surface but light from the typical distance of the shower maximum would be focused on the pixel entrance. Note that this offset may be impractically small with secondary mirrors reducing the plate scale. The direction of the incoming rays is not transformed into the normal plane of the focal surface, thus corresponding to pixels shifted w.r.t.\ to a plane.
