In the 4-2 configuration, the octagon contains five PMTs and detects light excited
and scattered by the 488-nm (blue) laser. One PMT in the octagon collects side
scatter (SSC) signals. The trigon contains two PMTs and detects light excited by
the 633-nm (red) laser. The 4-2 configuration octagon and trigon arrays have the
filter and mirror combinations shown in Figure 1-2, and Table 1-1 on page 19.
