Extended flux as calculated from the PIONIER survey (Lazareff et al. 2017) plotted against the normalised PAH luminosity from the ISO observations (Acke & van den Ancker 2004). For most disks, only an upper limit is given for one or more of the PAH features. In that case, the symbol indicates the actually observed luminosity, while the horizontal error bar indicates the luminosity including upper limits. The legend shows the name of each source.
