\caption{\label{comparison}Comparison of our results (bold face) with already published cluster 
parameters. The errors of the last digit are given in parentheses if available.  
If interstellar extinction was given in other photometric systems (* $RGU$, ** $uvby$) they 
were transformed to $E(B-V)$ as described in Sect.~\ref{results}. The following references, 
sorted by cluster and year, are given in the last column: (1) Jackson, 
Fitzgerald \& Moffat (1980); (2) Yadav \& Sagar (\cite{Yadav2002}); (3) Yilmaz (\cite{Yilmaz1970}); (4) 
Wramdemark (\cite{Wramdemark1978}); (5) Fitzsimmons (\cite{Fitzsimmons1993}); (6) Vogt \& Moffat (\cite{Vogt1972}); (7) 
Peterson \& Fitzgerald (\cite{Peterson1988}); (8) V\'azquez et~al. (2003); (9) Kharchenko et~al. (\cite{Kharchenko2005}); 
(10) Lindoff (\cite{Lindoff1967}); (11) Moffat \& Vogt (\cite{Moffat1975}); (12) Fenkart \& Binggeli (\cite{Fenkart1979}); 
(13) Topatkas (1981); (14) Piatti et~al. (\cite{Piatti1999}); (15) Rohlfs et~al. (\cite{Rohlfs1959});
