2 Sample and imaging

The photometry of the objects listed in Table 1 is based on images taken during a 14-night run in March 1998 on the 1.2 m telescope of the Observatoire de Haute-Provence (OHP). Unfortunately, half of the nights were lost due to bad weather, so the total amount of galaxies successfully imaged was 15. The frames are 40 minute B and 20 minute R exposures. We used the No. 2 Tektronix $1024 \times 1024$ CCD camera. The pixel scale is $0\hbox{$.\!\!^{\prime\prime}$ }69^{-1}$, giving a frame size of $11\hbox{$.\mkern-4mu^\prime$ }8 \times 11\hbox{$.\mkern-4mu^\prime$ }8$. The gain was set to $3.5\,\mathrm {e^-}$ per ADU, and the CCD was read out in the fast mode, with a readout noise of $8.5 \,\mathrm {e^-}$. Seeing was generally fair to poor, between $2\hbox{$.\!\!^{\prime\prime}$ }5$and $4\hbox{$.\!\!^{\prime\prime}$ }5$, but for our purposes the images were still useful. The data collected in Table 1 consists of the identification of the imaged galaxies in Cols. 2 and 3, their 2000.0 epoch coordinates in Cols. 4 and 5, types in Col. 6, with classification from Binggeli et al. (1990) marked with ^b, total B magnitude from the present photometry, except for galaxy #13, in Col. 7, heliocentric radial velocity in Col. 8 and photometric distances in the last column. All data except for those of the last column, the magnitudes and type data marked with ^b are taken from the NED. The photometric distances are from Makarova et al. (1997, 1998)$^{1,\,4}$, Tikhonov & Karachentsev (1998)² and Georgiev et al. (1997)³.
