Spectra and spectral classification of all Seyfert galaxy neighbours. Optical spectra were taken with the Boller & Chivens spectrograph mounted on the 2.1m telescope at the Observatorio Astronomico Nacional in San Pedro Martir (OAN-SPM). Observations were carried out during photometric conditions. All spectra were obtained with a 2.5" slit. The typical wavelength range was 4000-8000{AA} and the spectral resolution R=8{AA}. Spectrophotometric standard stars were observed every night. The data reduction was carried out with the IRAF package following a standard procedure. Spectra were bias-subtracted and corrected with dome flat-field frames. Arc-lamp (CuHeNeAr) exposures were used for wavelength calibration. We disentangled the spectral contribution of the host galaxy from the observed spectra by using the stellar population synthesis code STARLIGHT.
