Abstract:
    The Zurich Environmental Study (ZENS) is based on a sample of ~1500
    galaxy members of 141 groups in the mass range ~10^12.5-14.5^M_{sun}_
    within the narrow redshift range 0.05<z<0.0585. ZENS adopts novel
    approaches, described here, to quantify four different galactic
    environments, namely: (1) the mass of the host group halo; (2) the
    projected halo-centric distance; (3) the rank of galaxies as central
    or satellites within their group halos; and (4) the filamentary
    large-scale structure density. No self-consistent identification of a
    central galaxy is found in ~40% of <10^13.5^M_{sun}_ groups, from
    which we estimate that ~15% of groups at these masses are dynamically
    unrelaxed systems. Central galaxies in relaxed and unrelaxed groups
    generally have similar properties, suggesting that centrals are
    regulated by their mass and not by their environment. Centrals in
    relaxed groups have, however, ~30% larger sizes than in unrelaxed
    groups, possibly due to accretion of small satellites in virialized
    group halos. At M>10^10^M_{sun}_, satellite galaxies in relaxed and
    unrelaxed groups have similar size, color, and (specific) star
    formation rate distributions; at lower galaxy masses, satellites are
    marginally redder in relaxed relative to unrelaxed groups, suggesting
    quenching of star formation in low-mass satellites by physical
    processes active in relaxed halos. Overall, relaxed and unrelaxed
    groups show similar stellar mass populations, likely indicating
    similar stellar mass conversion efficiencies.

Description:
    The entire ZENS sample of 141 galaxy groups was selected from the
    2PIGG catalog (Eke et al. 2004, J/MNRAS/348/866), which is based on a
    friends-of-friends (FOF; Huchra & Geller 1982, VII/86) percolation
    algorithm thoroughly tested on realistic mock galaxy catalogs
    generated from cosmological N-body simulations. The 2PIGG catalog
    covers 1500deg^2^ of the 2dFGRS (Colless+, 2001, VII/250).

    The data were taken in several observing runs over the period
    2005-2009. Following a pilot-project time allocation in 2005, most of
    the observations were carried out as service-mode observations in the
    context of the ESO Large Program 177.A-0680. Paper II (Cibinel+,
    2013ApJ...776...72C) provides details of the observing runs, the raw
    data properties, the data reduction procedures, and the photometric
    calibration for WFI data of the ZENS groups.

Note (1): The observing run during which the WFI B- and I-band imaging was
          acquired for a given group; see Paper II (Cibinel et al.
          2013ApJ...776...72C).
Note (2):
  a = groups that satisfy the criterion for being "fossil" according to the
      definition presented in Section 2.4.
Note (3): Groups that have a velocity dispersion derived with the gapper
   estimator that is smaller than the typical 2dFGRS redshift error
   (~70-85km/s) have null {sigma} values in the original 2PIGG catalog
   (see Equation (4.6) in Eke et al. 2004, J/MNRAS/348/866). For these
   groups, the entry in the column for {sigma} lists "-70," i.e., the
   velocity dispersion is set equal to the 2dFGRS redshift error of
   70km/s at z~0.05 and the minus sign is used as a flag to identify the
   groups in question.
Note (4): Number of members above the magnitude limit of the survey.
Note (5): The value of LSS overdensity calculated with our fifth-nearest-group
          algorithm (log(1+{delta}_LSS_)).
Note (6): The overdensity quartile to which the groups belong relative to the
          global distribution of overdensities in the redshift window
          0.035<z<0.075 (with the first and fourth quartile indicating regions
          of the lowest and highest environmental density, respectively).

--------------------------------------------------------------------------------
Note (1): Projected sizes are converted into physical units assuming the
   following cosmological parameters: h=0.7, {Omega}_m_=0.3,
   {Omega}_{Lambda}_=0.7. Parameters which are not available are listed as:
   -99 entries for definite positive parameters, and +99 for definite negative
   parameters. For merging galaxy pairs we list parameters for both the primary
   and secondary galaxy, when available.
   Unless specified differently, all magnitudes and colors are in the
   AB system. For galaxies outside the WFI FOV all galactic parameters,
   except the stellar masses, are given as -99 entries.
Note (2): Galaxy weight accounting for 2dFGRS redshift incompleteness
   calculated as described in Section A.
Note (3): R200 radius derived from the group mass (see text).
Note (4): Defined as log(1+{delta}_LSS_) where {delta}_LSS_ is calculated to
   the fifth nearest 2PIGG group  (see text).
Note (5): Flag as follows:
   1 = group located in first quartile of the distribution of
       log(1+{delta}_LSS_);
   2 = second quartile;
   3 = third quartile;
   4 = fourth quartile.
Note (6): Flag as follows:
   0 = relaxed, nominal best-fit most massive galaxy is identified as
       "central" (and group center);
   1 = relaxed, a central galaxy satisfying criteria described of Section 3.2.1
       is identified, but it is not the nominal best-fit most massive galaxy
   2 = unrelaxed, no galaxy in the group satisfies the criteria in
       Section 3.2.1 to be a central, but nevertheless
       the nominal best-fit most massive galaxy is labeled as "central" and
       used as the group center.
Note (7): Flag as follows:
   0 = satellite;
   1 = central;
   2 = central if considering only galaxies with WFI B- and I-band imaging.
Note (8): For galaxies outside the WFI FOV the masses are inferred from the
   mass vs r_F_ magnitude relation as described in the text.
Note (9): Lower and upper limits corresponding to an increase of 50% of the
   best-fit {chi}^2^,  derived from the distribution of {chi}^2^ for
   all templates used in the ZEBRA+ SED fitting.
Note (10): Type as follows:
   0 = Elliptical;
   1 = S0;
   2 = Bulge-dominated spiral;
   3 = Intermediate disk;
   4 = late-type disk;
   5 = Irregular.
Note (11): Close pairs are identified as those galaxies which have a velocity
   difference, with respect to another group member, Dv<500km/s, and lie at
   a projected distance from the same member, dmax{<=}48arcsec (equal to the
   maximum separation between merging galaxies type=1 or type=2. This is
   about 50kpc at the typical ZENS redshift).
   0 = not merging;
   1 = plausible merger, no spectroscopic or photo-z confirmation;
 1.5 = same as flag 1 but visible tidal tails;
   2 = merger, spectroscopic or photo-z confirmation;
   3 = close pair among group members;
   4 = disturbed morphology.
Note (12): The parameter is corrected for observational biases as described
   in Paper II (Cibinel et al. 2013ApJ...776...72C).
Note (13): Together with the formal GIM2D errors we also provide an additional
   error which is obtained by the half difference between the single and double
   component half-light radii.
Note (14): Disk scale length from pure exponential GIM2D fit for the entire
   galaxy.  This scale length is only available for late-type disks (Mtype=4).
Note (15): GIM2D failed to provide some decompositions, which were successfully
   re-computed using GALFIT.
   * For I-band: 0=GIM2D, 1=GALFIT.
   * For B-band:
      0 = GIM2D unconstrained.
      1 = GALFIT.
      2 = average of GIM2D unconstrained and GIM2D with
          ellipticity/PA fixed to I-band.
      3 = GIM2D with ellipticity/PA fixed to I-band.
      4 = GIM2D with ellipticity/PA/bulge parameters fixed to I-band.
      5 = GIM2D with ellipticity/PA/bulge/disk parameters fixed to I-band.
Note (16): Special values:
  * -99 if no reliable decomposition is available.
  * -98 if galaxy has a late-type morphology and is best described by
     single component Sersic fit with n<1.5.
  * No bulge+disk decomposition is performed on galaxies classified as
    ellipticals, however we set B/T=1 in this catalogue for this
    morphological type.
Note (17): Obtained by integration to infinity of the bulge+disk surface
   brightness profiles.
Note (18): Non parametric structural index corrected for PSF and observational
   biases as described in Paper II.
Note (19): This is the actual Petrosian radius, not the default SEXTRACTOR
   Petrosian aperture which is 2.5 the Petrosian radius.
Note (20): Default SEXTRACTOR Kron aperture equal to 2.5 times Rkron.
Note (21):
   0 = not barred;
   1 = barred.
Note (22): Flag as follows:
   0 = quenched;
   1 = moderately star-forming;
   2 = strongly star-forming.
Note (23): Flag as follows:
   0 = the galaxy satisfies color-color and spectral criteria.
   1 = the galaxy has an actively star-forming spectrum but has red
       optical-UV colors.
   2 = the galaxy has a quenched spectrum but has blue optical-UV colors
       and strong Hdelta absorption.
   3 = the galaxy has a quenched spectrum, has blue optical-UV colors but
       no strong Hdelta absorption (see Paper III (Cibinel et al.
       2013ApJ...777..116C) for details).
Note (24): The SSFR for galaxies for which the best fit SED result in a
   SFR<10^-4^Msun/yr is set equal to sSFR=10^-14^yr^-1^.
   Likewise SFR<10^-4^Msun/yr are set to SFR=10^-4^Msun/yr.
Note (25): Magnitude computed in an elliptical aperture equal to 2 times the
   the largest Petrosian radius among the B- and I-band one.
   This data is used in the derivation of stellar masses.
Note (26): Sextractor MAG_AUTO
Note (27): These are the original b_j_ and r_F_ magnitudes, as released by
   the 2dFGRS team. The b_j_ magnitude is corrected for galactic extinction,
   but is not at the rest-frame. The r_F_ in not corrected for galactic
   extinction and is not at the rest-frame. Both are in the Vega system.
Note (28): 999 = undetected;
Note (29): Sum in quadrature of the magnitude errors deriving from the formal
   GIM2D uncertainty on the flux and on the bulge-to-total ratio.
   Bulge lower magnitude errors are set to 99 if erBT=0.
   Disk upper magnitude errors are set to 99 if ErBT=1.
Note (30): For the bulge and disk components the k-corrections are obtained
   from the observed colors and the relation between the k-correction
   and color as derived for the entire galaxies (see Paper III;
   Cibinel et al. 2013ApJ...777..116C).
Note (31): -99 if no reliable B+D decompositions are available in both B-
   and I-band or color cannot be reproduced by synthetic spectral library.
Note (32): Color gradients and color at the half-light radius corrected for
   observational biases as described in Paper III (Cibinel et al.
   2013ApJ...777..116C).
Note (33): This error reflects the S/N ratio obtained in the Voronoi bins at
   the galaxy half-light radius. It is set to 99 if tessellated map does not
   reach the half-light radius.
Note (34): Quadratic sum of the B-,I- surface brightness errors on a single
   pixel at the galaxy half-light radius. It is set to 99 if surface
   brightness in one of the two bands is below rms value of the sky.
Note (35): For a few galaxies classified as moderately or strongly star-forming
   from their spectral features or location on the NUV-optical color-color
   diagram the unconstrained ZEBRA+ fits give inconsistently low SFR and
   sSFR values. For these galaxies ZEBRA+ was re-run imposing a star-forming
   template model. The flag in this column identifies such galaxies and is
   set equal to the incorrect galaxy stellar mass from the unconstrained
   ZEBRA+ fits for the re-fitted galaxies and to -99 for all other galaxies
   (see Paper III (Cibinel et al. 2013ApJ...777..116C) for details).
Note (36):
   0 = no bright star/companion within Petrosian radius.
   1 = galaxy lies close to a bright star, the parameters for this galaxy may
       be subject to large uncertainties.
   2 = companion within the galaxy Petrosian radius.
   3 = bright clump/star-clusters within Petrosian radius.
Note (37): These parameters are used to calculate the magnitude and position
   dependent 2dFGRS redshift completeness at the ZENS galaxy positions.
   See Section 8 of Colless et al. 2001, VII/250 and Appendix A.
Note (38): This flag is equal to 1 if the given galaxy corresponds to the
   original 2PIGG group center, and otherwise equal to 0. For merging
   pairs/triplets, which have a single entry in the 2PIGG catalog, the
   flag is set equal for all merger members.
Note (39):
   0 = GIM2D and GALFIT I-band parameters agree within a factor of two;
   1 = At least one parameter differs more than a factor of two between the
       GIM2D and GALFIT I-band fits
 -99 = if either the GALFIT or GIM2D decomposition is not reliable/available
       (see Paper II; Cibinel et al. 2013ApJ...776...72C).
Note (40): The spectroscopic flag used, together with the color criteria
   described in Paper III (Cibinel et al. 2013ApJ...777..116C), to classify
   galaxies in strongly star-forming, moderately star forming and quenched
   systems (see also Figure 4 of Paper III).  Specifically,
    1 = no emission lines (in particular H{alpha} and H{beta});
    2 = H{alpha} and [OIII] or [OII] in emission, but no Hbeta;
    3 = strong emission in H{alpha}, H{beta}, [OII] and [OIII].
   The flag is negative (from -1 to -3) if the spectrum is probing only
   the galaxy central region (nuclear spectrum).
Note (41): M_20_ is the second-order moment of the brightest 20% of galaxy
   pixels (e.g., Abraham et al. 2003, J/ApJ/588/218; Lotz et al. 2004,
   J/AJ/128/163).
