 \tablefoot {In the following rows we present: the morphological type of the object (LEDA), the distance (Karachentsev et~al. \cite{Karachentsev2004}), the size calculated from $D_{25}$ (LEDA) and distance, the star formation rate (SFR), and the results of the radio analysis of Chy\.zy et~al. (\cite{Chyzy2000}, \cite{Chyzy2003}).}
