Effects of the interaction on the properties of spiral galaxies. I. the data

We have obtained Johnson B V I images and long slit spectra along the major axis of a sample of isolated spiral galaxies, and a sample of spirals in isolated pairs. We present in this contribution the photometric parameters (galactic orientation in the sky, total magnitudes and colors, color gradients, isophotal profiles and their decomposition in bulge and disk components) and the rotation curves of the observed galaxies. For some of the galaxies Ha images and/or spectra along the minor axis are also available and the data also presented here. The data we obtain are then compared with those reported in the RC3 catalogue. The analysis of both samples and their comparison will be published separately.
