$^a$ Identifications from V\'azquez \& Feinstein (\cite{VF91}); *~stands for member in NGC~5606  according to them.
$^b$ ${\sigma_{1}}^{2} = \sum {(r_{\lambda}/{\epsilon_{p_\lambda}})^2}/(m-2)$; where 
$m$ is the number of colors and $r_{\lambda} = P_{\lambda} - P_{\rm
max}~\exp(-K~\ln^2({\lambda_{\rm max}/{\lambda}))}$.
$^c$ Spectral type from the WEBDA database.
