\begin{list}{}{}

\item[$^1$] This galaxy is close to HDF3646+1408 ($z_{spec}=0.13$). 
   An aperture of $1.2''$ diameter is used for this object.  
\item[$^2$] This galaxy is within $3''$ of another object (Lanzetta et al 1997). An 
   aperture of $1.2''$ is used for this galaxy. 
\item[$^3$] A spectroscopic redshift of 0.13 is found for this galaxy (Cowie 1997). 
   However, this object is close to another galaxy 
   (HDF3646+1405) with $z_{spec} =0.96$ 
   and lies within $ 1''$ of 
   a brighter source. It is likely that the spectroscopic redshift of this 
   galaxy is in error. Lanzetta et al (1997) estimate a photometric redshift 
   of 1.2 for this object compared to our value of 0.675 (when using $1.2'' $
   aperture diameter). 
\item[$^4$] This galaxy lies within $1''$ of a slightly brighter galaxy with no available
    redshift. Lanzetta et al (1997) estimate a photometric redshift of 0.76
    for this object compared to our estimate of 0.925. It is likely that the 
    spectroscopic redshift of this object is in error due to confusion with 
    an overlapping source.   
\item[$^5$] This galaxy is undetected in the U-band and shows a very red $B-I$ colour. 
    It is likely that intervening absorbers have affected its SED.   
\item[$^6$] This object shows a very complex morphology with a disk galaxy a few
     arcsec to its southwest (Lowenthal et al 1997). An aperture of $1.2''$
     diameter is used for this galaxy.   
\item[$^7$] An aperture of $1.2''$ diameter is used for this galaxy due to close
companions.   
\item[$^8$] These objects are identified as UV `drop-outs' in Lowenthal et al (1997). 
   We assume $U=28.01$ mag. 
   An effective aperture of $1.2''$ diameter is used.   
\item[$^9$] This galaxy had been given a wrong spectroscopic redshift of 2.845. Its
   spectroscopic redshift was subsequently measured to be 2.008
   (Lanzetta et al 1997; Dickinson 1998).
