\caption {Table for derived quantities for the different regions. The
  last row gives the mean and standard deviation for all the
  regions. Column~2 is the SFR derived from the observed
  \halpha\ flux, and Col.~3 corrects the SFR for the extinction given
  in  Table~\ref{tab:emlines}. Column~4 gives the best fit age. The
  mass (Col.~5) is determined from population modelling. The mass to
  light ratio (Col.~6) uses the luminosity $L_B$ derived from the 
  $B$~magnitude relative to the {\it AB}~magnitude for the sun  $M_{B,{\odot}}=5.33$. Column~7 lists the specific SFR per Gyr
  normalised to the mass after correction for the host extinction, and
  Col.~8 lists the luminosity specific SFR, both derived after
  correcting for intrinsic extinction.
