2 The sample

The galaxies chosen for this study were selected to span as broad a range of nuclear magnitudes and optical line characteristics as possible and still be classified as Seyfert 1 or Narrow Line Seyfert 1 as is the case for 1H1934-063. For example, the Full-width half maximum of the H$\alpha$ line derived from spectroscopy varies from 2000 km s^-1 to 7000 km s^-1 and the contribution of the stellar population to the observed continuum varies from negligible up to 80% (Rodriguez-Ardila et al. 2000, hereafter RPD2000). These galaxies were selected from the compilation of many catalogs, mainly from the Calan Tololo Survey (Maza et al. 1989, 1992, 1994) and from the compilation of Véron-Cetty & Véron (1996). However, due to limitations of the available observing time and the location of the observatory, the exact sample was a randomly selected subsample of our entire list of Seyfert 1. Those with little or no photometric information available in the literature were chosen for this publication.

Figures 1a-j present our V images of the sample galaxies. We have observed them to obtain photometric parameters such as isophotal shapes, colors and luminosity profiles that can provide information on their basic properties and structure. As a secondary objective, we want to contribute to the available multicolor photometric data for Seyfert 1 galaxies, that is still far from being completed. The continuum and line emission properties of six objects of our sample (CTSC16, CTSF10.01, CTSA08, 1H2107-097, CTS G03.04 and 1H1934-063) were already studied by means of optical and near-IR spectroscopy (RPD2000).

The lower left bar represents 30'' and the corresponding projected scale in Kpc is also indicated. a) CTC C16.16, b) CTS G03.04, c) CTS A08.12, d) ESO 602- G031, e) ESO 025- G 002, f) 1H 1934-063, g) 1H 2107-097, h) ESO 354- G 004, i) MRK 0509, j) CTS F10.01.

The galaxies in our sample are listed in Table 1 along with information about their morphological type, magnitudes, extinction in blue band and radial velocities. These parameter were taken from the NED database. Throughout this paper we have adopted a Hubble constant H₀ = 75 km s^-1 Mpc^-1.
