* I call the these covers small (Figure 3 in the RPSS article) and large (Figure 4 in the RPSS article). The small size covers are 84cm wide and 175~200cm tall. The large size covers are 95.5cm wide and 220~240cm high. The variations in height noted here are because the covers were cut open and this usually reduced the top or bottom where they were opened.
