Table 1:
The detection rates of the PAH 3.3 
m feature in the ISO and ISAAC samples. T stands for the total of classified sample sources, I and II refer to the Meeus groups and E represents the
embedded sources. The last
row gives the detection rates in the combined ISO+ISAAC sample. When
two percentages are given, the second refers to the detection rate
including tentative detections. The detection rate in group I is
significantly higher than in group II (confidence level >99.5%).
