The distances from the mirror centers towards # the center of the focal plane are chosen to form a Hybrid reflector # half Davies Cotton half Paraboloid. # # The mirror orientation is measured using the advanced SCCAN system # made for FACT's alignment. Here the orientations are expressed using # the normal vector of the mirror facets Nx, Ny and Nz. # # Focal length f is taken from Ann-Kristin Overkemping's Diploma Thesis: # Justage der Spiegel und Simulation der realen # Reflektorgeometrie fuer FACT # # The mirror diameter fD is taken to be equal for all mirrors and has # not been measured again. # # The ID is the number written on the back of the actual mirrors mounted # on FACT. It is the same ID numbering as used in Ann-Kristin # Overkemping's Diploma Thesis. # # A detailed description of the calculations towards this numbers is # found in Sebastian Mueller's Master Thesis, see appendix: # Clear Sight # in Cherenkov Astronomy # Investigations of Reflector Geometry # and Mirror Alignment for the # FACT Telescope
