- Description:
- The Sloan Digital Sky Survey (SDSS) has observed more than a quarter of the sky over eight years of operations, obtaining multicolor photometry and spectroscopy for ~ 1 million of galaxies. A catalog of photometric redshifts for ~ 2 millions quasars with magnitude r < 20.7 extracted from the SDSS DR7 dataset (D'Abrusco et al, 2009) is provided here. The photometric redshifts and the uncertainty of the estimates for each sources have been calculated using the Weak Gated Expert (WGE) method. The WGE (Laurino et al., submitted to MNRAS) is based on the exploitation of the spectroscopic redshifts for a subset of photometric sources and derives photometric redshifts through a combination of data mining techniques. This method can be applied to different classes of extragalactic sources and is scalable. A set of observational parameters used for the evaluation of photometric redshifts, the estimated photometric redshifts values and some of the most common observational parameters retrieved from the SDSS database have been included in the catalog for the sake of simplicity.

- Publisher:
- IA2
- Description:
- The catalogue contains a total number of ~39 900 galaxies, for which we provide the automated estimates of the morphological type, applying the purposely devised tool MORPHOT to the V-band WINGS imaging. The used tool is non-parametric and fully empirical. In particular, MORPHOT exploits 21 morphological diagnostics, directly and easily computable from the galaxy image, to provide two independent classifications: one based on a maximum likelihood (ML), semi- analytical technique and the other one on a neural network (NN) machine. A suitably selected sample of ∼1000 visually classified WINGS galaxies is used to calibrate the diagnostics for theML estimator and as a training set in the NN machine. The final morphological estimator combines the two techniques. (http://adsabs.harvard.edu/abs/2012MNRAS.420..926F)

- Title:
- WINGS local densities (Mv<-19.5)
- Short Name:
- WINGSLocDens19.5
- Date:

- Publisher:
- IA2
- Description:
- For each WINGS galaxy with V absolute magnitude brighter than -16, the local density calculated as the Log (decimal) of the number of galaxies with M_V <= -19.5 per Mpc**2 is given. It is computed from the circular area enclosing the first 10 closest galaxies, plus the background counts expected from Berta et al. (2006). The Local Densities are also corrected for border effects. The Coverage field fraction are also given, both at CCDX, i.e. the fraction of the circular area of radius CCDX and centered in the X-ray center, which is included in the field of the CCD mosaics, and at CCDB (centered in the BCG). For clusters without velocity dispersion the distances are given in pixels and NOT in R200. These clusters are A311, A2665, A3164, and Z1261.

- WINGS V surface photometry
- Short Name:

- Date:

- Publisher:
- IA2
- Description:
- This catalog contains the surface brightness measurements of ~42250 galaxies detected in the V images of the WINGS cluster survey. For each galaxy V magnitude, mean surface brightness, effective radius, Sersic index and axial ratio are given, together with their errors. These global parameters were obtained by simultaneously fitting the major and minor axis light growth curves of galaxies with a 2D flattened Sersic-law, convolved by the appropriate, space-varying PSF, which was previously evaluated by the tool itself.

- Description:
- This catalog contains the surface brightness measurements of ~71700 galaxies detected in the K images of the WINGS cluster survey for a subsample of 26 clusters observed with the UKIRT WFCAM. For each galaxy K magnitude, mean surface brightness, effective radius, Sersic index and axial ratio are given, together with their erros. These global parameters were obtained by simultaneously fitting the major and minor axis light growth curves of galaxies with a 2D flattened Sersic-law, convolved by the appropriate, space-varying PSF, which was previously evaluated by the tool itself.

- Description:
- This catalog contains the surface brightness measurements of ~41500 galaxies detected in the B images of the WINGS cluster survey. For each galaxy B magnitude, mean surface brightness, effective radius, Sersic index and axial ratio are given, together with their errors. These global parameters were obtained by simultaneously fitting the major and minor axis light growth curves of galaxies with a 2D flattened Sersic-law, convolved by the appropriate, space-varying PSF, which was previously evaluated by the tool itself.

- Title:
- WINGS equivalent widths
- Short Name:
- WINGSEqwidth
- Date:

- Publisher:
- IA2
- Description:
- The catalog gives the measurements of the optical lines equivalent widths and statistical errors for a sample of ~4400 objects detected in 48 WINGS clusters for which the spectrum is available and reliable. Emission lines have negative EWs, and absorption lines positive EWs, with all the quantities given at rest frame. Spectra were obtained with WYFFOS@WHT and 2dF@AAT and have a resolution of 6 and 9 AA FWHM, respectively. The wavelength coverage ranges from ∼ 3590 to ∼ 6800 AA for the WHT observations, while spectra taken at the AAT cover the ∼ 3600 to ∼ 8000 AA domain. For each object the catalog gives also the magnitude and radial completeness (or weight) that, once combined, describe the global completeness of the sample. Finally a spectral classification is available, made on the basis of the presence/absence and intensity of spectral lines (following Poggianti et al., 1999): 1=e(a); 2=e(b); 3=e(c); 4=k; 5=k+a; 6=a+k.

- Publisher:

- Description:
- DOLORES (Device Optimized for the LOw RESolution) is a focal reducer instrument installed at the Nasmyth B focus of the TNG. The detector is a 2048 x 2048 E2V 4240 Thinned back-illuminated, deep-depleted, Astro-BB coated CCD with a pixel size of 13.5 µ. The scale is 0.252 arcsec/px which yields a field of view of about 8.6 x 8.6 arcmin. The instrument allows imaging through broad and narrow band filters as well as spectroscopic observations with resolving powers between RS=~500 and RS=~6000. A multi-slit mode, based on custom masks manufactured by a dedicate cutting machine, is also available. Please note that MOS programs are bound to strict constraints on the number of masks and on the time necessary to design and manufacture them. In particular, each program can request up to a maximum of 5 masks per night and 10 masks per observing run.
