The arrangement of the CCDs in the focal plane. Top: schematic of the butting of the CCDs. Green indicates the active area of Si. Bottom: the detector array integrated into the VIS bracket on the telescope baseplate, showing the spacing of the CCD and the wire bonds from the active Si to the flexible connections at the top and bottom of each CCD, as well as the two pairs of Fine Guidance Sensor CCDs above and below the VIS Focal Plane Array.
