130, 968 (http://adsabs.harvard.edu/abs/2005AJ....130..968M)
- CMU-PITT SDSS Value Added Catalog (VAC):
a database that allows users to conduct scientific analyses on the SDSS spectroscopic galaxy data. It
allows for easy use of spectral information (i.e. emission line-widths), and
for anybody to upload Science Derivatives for SDSS galaxies.
- Composite broad-absorption line (BAL) quasar spectra: as a
function of BALQSO type from
et al. 2003, A Catalog of Broad Absorption Line Quasars from the Sloan Digital Sky
Survey Early Data Release, AJ, 125, 1711 and Reichard
et al. 2003, AJ 126, 2594, Continuum and Emission-Line
Properties of Broad Absorption Line Quasars. We provide
this tarball of composite BAL
quasar spectra from the SDSS Early Data Relase; see the
enclosed README file for more information.
- Composite red quasar spectra: As described in Richards
et al. 2003, AJ 126, 1131, Red and Reddened Quasars in
the SDSS, these spectra are composites as a function of
relative g-i color, with input objects normalized
such that both the absolute magnitude and redshift distributions
are the same in like composites. We provide this tarball of composite red quasar
spectra for download.
- The SDSS Cut & Enhance
galaxy cluster catalog The Sloan Digital Sky
Survey CE galaxy cluster catalog (Goto
et al. 2002, AJ 123, 1807) uses color cuts
combined with a density enhancement algorithm to detect clusters
of galaxies. The SDSS CE galaxy cluster catalog contains an
estimated redshift and richness for each cluster found in 350
sq. deg. of SDSS commissioning data.
- The Light-Motion-Curve Catalogue (LMCC) and Higher-Level Catalogue (HLC):
Light and motion in SDSS Stripe 82: the catalogues,
by Bramich, Vidrih, Wyrzykowski et al. 2008 MNRAS 386, 887.
- The MaxBCG Catalog of 13,823 Galaxy Clusters: Koester, B.P. et al 2007 ApJ 660,
- The Fourth Data Release of the
SDSS Moving Object Catalog: lists astrometric and
photometric data for 471,569 moving objects observed prior to March
2007. Of those, 220,101 are linked to 104,449 unique objects from
the ASTORB file, and their orbital
elements are also listed. This is a cumulative release, and it
supersedes the previous versions (first
MOC release, second
MOC release, and third
- MPA/JHU value-added galaxy catalog:
contains results from a custom galaxy spectral fitting code (line fluxes, continuum indices,
line widths, EWs etc.) mostly written by Christy Tremonti and described in
Tremonti et al (2004).
The following derived data are also available:
- NYU Value-Added Galaxy Catalog:
a cross-matched collection of galaxy catalogs, including the SDSS,
maintained for the study of galaxy formation and evolution. It includes
carefully constructed large-scale structure samples useful for calculating
power spectra, etc, and includes, e.g., the "LSS Sample12" described in
various Blanton et al. and Tegmark et al. SDSS papers.
- The SDSS
Orion data release contains imaging near the Galactic plane outside
of the nominal survey boundaries, and the runs are not part of the standard
SDSS data releases. This public release of about 470 square degrees includes
the star-forming region NGC 2068/NGC 2071/HH24 and a large part of Barnard's
Finkbeiner et al. 2004 AJ 128, 2577
Galaxy Groups and Clusters: Berlind, A.A. et al 2006 ApJS
- Photometric Redshift 2 catalog, with probability distributions:
contains links to a text version of the photoz2 table of the CAS,
with additional columns representing the probability distribution
function (PDF) for each object with a photometric redshift. The
PDF for each object consists of values between 0 and 1 in 100
redshift bins which run from 0.03 to 1.47 where dz = 1.44/99. The
PDF information is only available as a value-added catalog,
whereas the photometric redshift catalog is available in the CAS
for SQL searches (joined to the main galaxy database). The
catalog was developed by Huan Lin of Fermilab, Carlos Cunha of the
University of Michigan and collaborators at the University of
Chicago: Cunha et al. (2009). The README file contains column descriptions.
- The Princeton spectra
are the newer of two parallel codes to determine spectroscopic classification and redshift; they are
also known as SpecBS. The determination of redshifts and classifications direct chi-squared fitting
of templates to spectra. These reductions are included in DR7, with documentation available
at the Princeton Spectra site.
- Fourth edition of the SDSS Quasar
Catalog: As decribed in Schneider
et al. 2007, AJ 134, 102, this catalog contains 77,429
quasars from DR5 that have i-band luminosities brighter than -22,
at least one broad emission line, and highly reliable
redshifts. The catalog is now available in ASCII and FITS binary
- Redshifts for DR7 Quasars,
generated using the
Hewett and Wild scheme,
of the SDSS DR7 Legacy Release spectra of the objects in the
et al. (2010) quasar catalogue. A total of 107194 spectra/objects
are included. Release-specific information is described in the
SDSS Stripe 82 Standard Star Catalog, as reported by Ivezic
et al. 2007, AJ 134, 973, lists positions and 1% ugriz
photometry for a million candidate standard stars from SDSS
stripe 82 (|Dec|<1.266 deg and RA in the range 20h 34m to 4h
00m; about 300 sq.deg.).
The SDSS-I Stripe 82 Variable Star Catalog, as reported by

(median magnitudes), and various low-order lightcurve statistics
for 13,051 candidate variable sources.

corresponding to Kessler et al 2009.

catalog: As reported in the paper Space Density of
Optically-Selected Type 2 Quasars by Reyes, Zakamska, Strauss et
al. 2008 (submitted to Astronomical Journal; arXiv:0801.1115). The
catalog contains 887 objects from post-DR5 data.
- The 2SLAQ LRG Catalog: As described in
Cannon et al. 2006
(MNRAS, 372, 425 (2006)),
this is a spectroscopic survey of nearly 15,000 intermediate-redshift
luminous red galaxies (LRGs) brighter than i=19.8, selected
from SDSS photometry and observed with the 2dF spectrograph
on the AAT to probe higher redshift and lower luminosity
galaxies than the SDSS LRG sample, over an area of 180 deg2.
- The 2SLAQ Quasar Catalog:
As described in Croom et al. in press
(MNRAS, in press, ArXiv:0810.4955), this is a spectroscopic catalog of 16,326 objects, 8,764 of
which are quasars, selected from SDSS imaging and observed with the 2dF spectrograph
on the AAT to create a sample roughly 2.5 magnitudes deeper than the low-redshift (z<3)
SDSS spectroscopic quasar sample over an area of 192 deg2.

SDSS and followup spectra of all 23 objects, plus IRAF and SM code for
calculating the traditional and revised balnicity indices, are available in a
gzipped tar file.
