EFFECTS OF THE INTERACTION ON THE PROPERTIES OF SPIRAL GALAXIES .1. THE DATA

We have obtained Johnson BVI images and long slit spectra along the ma jor axis of a sample of isolated spiral galaxies, and a sample of spir als in isolated pairs. We present in this contribution the photometric parameters (galactic orientation in the sky, total magnitudes and col ors, color gradients, isophotal profiles and their decomposition in bu lge and disk components) and the rotation curves of the observed galax ies. For some of the galaxies Her images and/or spectra along the mino r axis are also available and the data also presented here. The data w e obtain are then compared with those reported in the RC3 catalogue. T he analysis of both samples and their comparison will be published sep arately.
