Notes. Near-infrared sizes correspond to half-flux radius of a ring model. Mid-infrared data are the half-flux radius adapted from Varga et al. (2018). Multiplicative factor f is applied to the measured N-band characteristic size. The first column reports the numbering of Table 1. The last column gives the type of the silicate feature (a: absorption; e: emission; w: weak or flat) as provided in Table E.1 of Varga et al. (2018). (*) From Menu et al. (2015); (+) from Furlan et al. (2009).
