from front to back is the same as Table 2-3. The same information is given quantitatively in<br />
Table A-4 of Appendix A. Table A-5 presents mean source profiles for experiment 3, “alternate<br />
source profiles.”<br />
The on-road mobile source gasoline exhaust profiles (first four A-<strong>34</strong> categories at the front of<br />
Figure 2-5) are similar, which they should be since all are based on similar fuel composition.<br />
We deliberately selected mobile source profiles that reflected the same type of fuel so that the<br />
experiments would be closer to real-world conditions. The source profiles for solvents, coatings<br />
and industrial sources toward the back of Figure 2-5 have peaks for many species that are low in<br />
the mobile source profiles toward the front of Figure 2-5. There also are species that are high in<br />
mobile and non-mobile source profiles such as ethane, the left most species in Figure 2-5.<br />

Figure 2-5. Mean source profiles for experiment 1. The profiles are for 55 PAMS species over 22<br />
source categories. These are mean profiles because each A-<strong>34</strong> category may combine several<br />
SCCs that have different speciation profiles.<br />
2.5 SUPPORTING INFORMATION FOR ROUND 2<br />
In Round 2, DRI analyzed the same experiments as in Round 1 but was provided with additional<br />
information that a receptor modeler would typically have available to support a “real-world”<br />
receptor model application. DRI requested information on:<br />
