This galaxy has several other spectra obtained in sequences at adjacent slit positions covering a short wavelength range (6482Å-7054Å and 8275Å-8847Å). The 1d extractions can be recovered from the tar file M87.tar
. Relevant information for each spectrum from which the extraction was obtained, is listed in the Mastertable. Some of these spectra could be combined because correspond to same location in the galaxy. These combinations are also included in the tar file and identified by the following naming convetion: name of the galaxy followed by a sequence of numbers corresponding to each spectrum used in the combination (e.g. m87-67 means the combination of the spectra m87-6.62 and m87-7.62, while m87-1and2 means the combination of the spectra m87-1.62 and m87-2.62).
