 Notes to Table ~\ref{dusttab}:  Col.~(2) lists morphology of dust: dust ring(s) -- face on dust ring(s); maj.dust lane -- dust lane along the optical major axis; min. dust lane -- dust lane aligned along minor axis; multi. lanes -- multiple dust lanes;  dust clouds -- dust distribution in the form of clouds; nucl. dust~-- nuclear dust. Columns~(3) and~(4) list IRAS~flux densities at $\rm 60~\mu m$ and $\rm 100~\mu m$ (taken from Knapp et~al. \cite{Knapp1989}). Columns (5) and (6) list dust masses derived from IRAS~flux densities ($M_{\rm d,IRAS}$) and optical extinction values ($M_{\rm d,optical}$), respectively. Column~(7) gives dust temperature ($T_{\rm d}$), while Col.~(8) lists the present day mass-loss rate from the evolved, red-giant stars in the program galaxies. Column (9) lists  life time of dust grains derived using Eq.~(\ref{tau-d}).
