THE MORPHS Spectral Catalog

There is a UK Mirror of this site at Durham.

This page gives the links to the spectral catalog and spectra we have collected for the 10 clusters in the MORPHS sample. All files are provided as uuencoded gzipped TAR files, ASCII or Postscript. The data presented here include positions, photometry, redshifts, spectral line strengths and classifications for 657 galaxies in the fields of the 10 clusters. The catalog comprises 424 cluster members across the 10 clusters and 233 field galaxies, with detailed morphological information from our WFPC2 images for 204 of the cluster galaxies and 71 in the field. Full details of our analysis and the contents of the catalogs are given in Dressler et al. (1999). While the analysis and modelling of these data is discussed in Poggianti et al. (1999). Most of the information provided here will also appear on the ApJ web site.

CATALOG

The full ASCII catalogs of members and non-members are available here. The full catalogs from Dressler et al. (1999) are also available in TeX format in this TAR file. A brief explanation of the material contained in the ASCII tables is given here, more information can be found in Dressler et al. (1999). The links labelled `FITS Spectra' in the table below contain the TAR files with spectra of all the galaxies observed within each of our cluster fields (both members and non-members). The entire sample is available here.

IMAGES

The Postscript mosaics of the complete galaxy catalog(Fig. 8 from Dressler et al. 1999), split into members and non-members and broken down into the different spectral classes is in this TAR file.

The following mosaics are made from the WFPC2 images using the spectroscopic catalog to define the spectral types of the cluster galaxies. These only show galaxies in Cl0016+16, Cl0024+16, Cl0054-27, Cl0412-65, A370#2 and Cl0939+47#2, for which we have WFPC2 imaging in two passbands.

K-type Members  This mosaic shows `true' color images of the 47 members with k spectral types. The individual sub-images are 7×7 arcseconds in size and are made from the F555W/F814W images. The `golden' color of some of the galaxies is because those lie in Cl0024+16 where we have F450W imaging rather than F555W. The galaxies are ranked in morphological class, starting with the ellipticals at the bottom.

non-K-type Members  The mosaic below shows the `true' color images of the 42 member galaxies in the 6 cluster fields which have spectral types other than k. The images are made from the F555W or F450W and F814W images and are 7×7 arcseconds. The seven rows (starting from the bottom) contain: 1-2) k+a, 3) a+k, 4) e(a), 5) e(c), 6) e(b), 7) e and ?. The intensity and color scaling is the same as that used in the k-type plot above.

Field Galaxies  The plot above gives the `true' color images of the 21 field galaxies lying within the cluster fields. Again, the individual sub-images are 7×7 arcseconds and are made from the F450W/F555W and F814W images. The six rows show: 1) k, 2) k+a, 3) e(a), 4) e(c), 5) e(b), 6) e and ?, read from the bottom of the plot upwards. The intensity and color scaling is the same as that
