2 Observations and photometry

The first four galaxies were observed in February 1995 at the 2.5-m Nordic telescope with a subarcsec seeing. A CCD chip of 1 K $\times$ 1 K pixels provided a field of view of $3\hbox{$^\prime$ }\times3\hbox{$^\prime$ }$ with a resolution of $0\hbox{$.\!\!^{\prime\prime}$ }176$/pixel. The last two galaxies were observed on March-June 1997 at the prime focus of the 6-m telescope where a CCD camera provided a field of $2\hbox{$.\mkern-4mu^\prime$ }3\times2\hbox{$.\mkern-4mu^\prime$ }3$ with a resolution of $0\hbox{$.\!\!^{\prime\prime}$ }137$/pixel. The average seeing was about $1\hbox{$.\!\!^{\prime\prime}$ }5$. The exposure times in the B, V, R, I filters of Johnson-Cousins system, as well the seeings (FWHM) are given in Table 1. Equatorial standards from Landolt (1992) were used for the frame calibration.

Photometry of stellar objects in these galaxies was carried out with the DAOPHOT/ALLSTAR package (Stetson 1987). In some cases of crowded stellar field with high brightness gradients we repeated photometry after subtracting their frames smoothed with a median filter.
