2 List of dwarf galaxy candidates in the ESO/SERC zone

The results of our search for dwarf galaxy candidates are presented in Table 1. The table columns contain: (1) running number; (2) 1950.0 epoch (upper line) and 2000.0 epoch (lower line) equatorial coordinates; (3) major and minor diameters measured visually with an accuracy about 15% on blue (upper line) and red (lower line) films, respectively; (4) morphological type in the usual designations; (5) rough estimate of the mean surface brightness: H - high $\sim$(22-23) mag/ $\ifmmode\hbox{\rlap{$\sqcap$ }$\sqcup$ }\else{\unskip\nobreak\hfil

\parfillskip=0pt\finalhyphendemerits=0\endgraf}\fi\hbox{$^{\prime\prime}$ }$), VL - very low ($\sim$25 mag/ $\ifmmode\hbox{\rlap{$\sqcap$ }$\sqcup$ }\else{\unskip\nobreak\hfil

\parfillskip=0pt\finalhyphendemerits=0\endgraf}\fi\hbox{$^{\prime\prime}$ }$); (6) total apparent blue magnitude from the NASA Extragalactic Database (= NED) and galactic extinction from Schlegel et al. (1998) in the upper and lower lines, respectively; in many cases where $B_{\rm t}$ values are absent in NED we estimated total blue magnitudes visually with an error of $\sim$0.5 mag based on the galaxy dimension and surface brightness; (7) galaxy name in other catalogues and lists as given in NED; (8) comments concerning galaxy membership, morphology and radial heliocentric velocity.

Figure 1 displays $5\hbox{$^\prime$ }\times5\hbox{$^\prime$ }$ images of 81 dwarf galaxy candidates taken from the Digitized Sky Survey. The objects of extremely low surface brightness are practically invisible on the DSS.
