Schematic of a fixed target with the parameters labelled. (a) shows the entire fixed target, which comprises 64 city blocks with outer dimensions of approximately 30 × 30 mm. Each city block contains 400 apertures. There is a fiducial marker for alignment at each corner of the fixed target. (b) highlights a subregion of the fixed target showing a single city block. Distance values for this and other fixed targets are given in Table 2. |
