Notes. HAEBE disc group classification from Meeus et al. (2001), Acke et al. (2010), and Maaskant et al. (2013). “TO” stands for “Transition Object”, indicating that it lacks a near-IR excess. LUV is determined differently for the HAEBEs and the TTS, as described in the text (see Sect. 2);
LUV estimated from accretion luminosities. LPAH is from the survey by Acke et al. (2010) which includes our HAEBE sample; with “–”, we indicate a non-detection. In the column “CO det.”, we indicate whether there was CO emission detected in our PACS spectra (Y) or not (n).
