• 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. (DR3 catalog)
• Composite broad-absorption line (BAL) quasar spectra: as a function of BALQSO type from Reichard 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): described in 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, 239 (https://ui.adsabs.harvard.edu/abs/2007ApJ...660..239K)
• 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 MOC release).
• 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:
  • Stellar masses following the precepts of Kauffmann et al. (2003)
  • Star formation rates following Brinchmann et al. (2004)
  • Gas-phase metallicities as in Tremonti et al (2004)
• 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 loop. See Finkbeiner et al. 2004 AJ 128, 2577
• Percolation Galaxy Groups and Clusters:  Berlind, A.A. et al 2006 ApJS 167, 1 (https://ui.adsabs.harvard.edu/abs/2006ApJS..167....1B)
• 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 table format.
• Redshifts for DR7 Quasars, generated using the Hewett and Wild scheme, of the SDSS DR7 Legacy Release spectra of the objects in the Schneider et al. (2010) quasar catalogue. A total of 107194 spectra/objects are included. Release-specific information is described in the README file.
• 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 Sesar et al. 2007, AJ 134, 2236, lists positions, ugriz photometry (median magnitudes), and various low-order lightcurve statistics for 13,051 candidate variable sources.
• Supernova Light Curve Fits contains the light curve fit results corresponding to Kessler et al 2009.
• Type 2 (Obscured) Quasar 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.
• ugriz DAOPHOT photometry of SDSS+SEGUE Globular and Open Clusters: by Deokkeun An and Jennifer Johnson, papers to be submitted.
• SDSS Unusual BAL Quasars: A sample of 23 unusual Broad Absorption Line Quasars has been assembled from both the SDSS EDR and some post-EDR data.  Calibrated 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.
  • gzip-compressed PostScript file (2.3 Mbytes) of Hall et al. 2002, ApJS 141, 267
  • gzip-compressed tar file sb1data.tar.gz (1.1 Mbytes) containing spectra of all unusual BAL quasars in the paper along with the IRAF and SM code for calculating traditional and revised balnicities.
• The DR4 White Dwarf Catalog: as reported by Eisenstein et al. 2006, ApJS 167, 40, A Catalog of Spectroscopically Confirmed White Dwarfs from the Sloan Digital Sky Survey Data Release 4. The catalog contains 9,316 spectroscopically confirmed white dwarfs and 928 hot subdwarfs (DR1 catalog).
