Ho IX and NGC 2976 are too large to be reasonably
photometered with the 
Tektronix 
CCD camera's limited field of view. Therefore the given values of
the different parameters should be taken as lower or upper limits
respectively.
The radial profile of BK 5N seems to indicate a "nucleus'' apparent in the R band only. It appears on HST images that this feature is in fact a background galaxy (Caldwell et al. 1998).
Kar 61 is classified in this paper as a dE,N. This galaxy has recently been shown by Johnson et al. (1997) to contain a ionHii region, and they suggest that this galaxy might be a dwarf irregular.
DDO 71 seems to have an "off centre'' nucleus, see Fig. 1 (click here).
