This galaxy has several other spectra obtained in a sequence at adjacent slit positions wich cover a short wavelength range (4818Å-5104Å and 5236Å-10266Å) and several spectra obtained 0.1 arcsec offset from nucleus. The 1d extractions can be recovered from the tar file NGC4151.tar
. Relevant information for each spectrum from which the extraction was obtained, is listed in the Mastertable.
