Abstract:
We present the first public data release of the GOGREEN (Gemini
Observations of Galaxies in Rich Early Environments) and GCLASS
(Gemini CLuster Astrophysics Spectroscopic Survey) surveys of galaxies
in dense environments, spanning a redshift range 0.8<z<1.5. The
surveys consist of deep, multiwavelength photometry and extensive
Gemini GMOS spectroscopy of galaxies in 26 overdense systems ranging
in halo mass from small groups to the most massive clusters. The
objective of both projects was primarily to understand how the
evolution of galaxies is affected by their environment, and to
determine the physical processes that lead to the quenching of star
formation. There was an emphasis on obtaining unbiased spectroscopy
over a wide stellar mass range (M≳2x1010M☉), throughout and
beyond the cluster virialized regions. The final spectroscopic sample
includes 2771 unique objects, of which 2257 have reliable
spectroscopic redshifts. Of these, 1704 have redshifts in the range
0.8<z<1.5, and nearly 800 are confirmed cluster members. Imaging spans
the full optical and near-infrared wavelength range, at depths
comparable to the UltraVISTA survey, and includes Hubble Space
Telescope/Wide Field Camera 3 F160W (GOGREEN) and F140W (GCLASS). This
data release includes fully reduced images and spectra, with
catalogues of advanced data products including redshifts, line
strengths, star formation rates, stellar masses, and rest-frame
colours. Here, we present an overview of the data, including an
analysis of the spectroscopic completeness and redshift quality.
Description:
The design of the Gemini CLuster Astrophysics Spectroscopic Survey
(GCLASS) and Gemini Observations of Galaxies in Rich Early
Environments (GOGREEN) surveys is described in
Muzzin+ (2012ApJ...746..188M 2012ApJ...746..188M) and Paper I (Balogh+ 2017MNRAS.470.4168B 2017MNRAS.470.4168B),
respectively. See Section 2.
All SpARCS clusters have shallow imaging from the SWIRE survey
(Lonsdale+ 2003PASP..115..897L 2003PASP..115..897L), from which the clusters were
identified. Deeper channel 1 and 2 data exist for most of the
clusters, from SERVS (Mauduit+ 2012PASP..124..714M 2012PASP..124..714M), S-COSMOS
(Sanders+ 2007ApJS..172...86S 2007ApJS..172...86S), SpUDS (PI J. Dunlop, as described in
Galametz+ 2013, J/ApJS/206/10), and GTO programs 40033 and 50161
(PI G. Fazio). The remaining clusters were observed as PI programs
(PI Brodwin, from program ID 70053 and 60099 and McGee, program
13046). Some MIPS data from SWIRE and GTO programs 40033 and 50161
(PI G. Fazio) are available for the SpARCS clusters, but these are not
used in the analysis nor included in this release. See Section 3.1.1.
The deep GMOS imaging in z' obtained as part of GOGREEN is described
in Paper I (Balogh+ 2017MNRAS.470.4168B 2017MNRAS.470.4168B).
GCLASS z' imaging was obtained from CTIO and Canada-France-Hawaii
Telescope (CFHT), as described in Wilson+ (2009ApJ...698.1943W 2009ApJ...698.1943W) and
Muzzin+ (2009ApJ...698.1934M 2009ApJ...698.1934M & 2012ApJ...746..188M 2012ApJ...746..188M).
See Section 3.1.2.
A significant effort was undertaken to obtain deep imaging for all
GOGREEN systems outside the COSMOS and SXDF fields. New and archival
data were obtained from Subaru, VLT, Magellan, Blanco, and CFHT,
spanning the full observable optical/infrared wavelength range from u
to K. These data and basic processing steps are described in
van der Burg+ (2020A&A...638A.112V 2020A&A...638A.112V).
For GCLASS, optical ugriz data for the northern clusters were obtained
with MegaCam at CFHT. The southern clusters were imaged in ugri with
IMACS on Magellan, while the z'-band imaging came from the MOSAIC-II
camera on the Blanco telescope at CTIO. These data are described in
van der Burg+ (2013A&A...557A..15V 2013A&A...557A..15V). Near-infrared imaging of the GCLASS
systems from CFHT, Blanco, and VLT is described in
Lidman+ (2012MNRAS.427..550L 2012MNRAS.427..550L). See Section 3.1.3.
New HST/Wide Field Camera 3 (WFC3) F160W imaging for the 12 GOGREEN
clusters was obtained in a Cycle 25 program (GO-15294: PI Wilson).
We also provide the WFC3 F140W imaging obtained for the 10 GCLASS
clusters, described in Matharu+ (2019MNRAS.484..595M 2019MNRAS.484..595M).
See Section 3.1.4.
The GCLASS spectroscopy is described in Muzzin+ (2012ApJ...746..188M 2012ApJ...746..188M).
All the data were obtained with GMOS-S and GMOS-N. See Section 3.2.1.
A full log of the GOGREEN spectroscopic observations is given in
Table F1. Like GCLASS, spectroscopy was obtained with the GMOS-S and
GMOS-N instruments, but with a single pointing per cluster.
See Section 3.2.2.

Note (1): The first digit identifies the origin of the spectrum:
1 for GOGREEN and 2 for GCLASS.
The next two digits correspond to the cluster_id identifier in the
Cluster catalogue, which specify the photometric field.
The remaining digits are the galaxy ID (only unique for a given field and
source).
Note (2): Target coordinates, in J2000 degrees. For GOGREEN, these coordinates
correspond to the z' image coordinates used for mask design. These
have been transformed to align with the Ks images; however, positions
will not match exactly with coordinates in the photometric catalogues.
Note (3): This has a value of 1 for GOGREEN primary targets,
i.e. those that match our photometric selection criteria. A value of 3
corresponds to a GOGREEN "mask-filler" object, and 4 identifies a
GCLASS spectrum. (OBJClass=2 was reserved for stellar sources used for
telluric correction, and these are not included in the catalogue).
Note (4): Both quality 3 and 4 are secure galaxy redshifts and can be used for
scientific analysis; the difference between them is subjective and not
rigorously defined. Quality 2 is a "best guess" but should be used
with caution; this includes cases where there is plausible consistency
with the photometric redshift, but no clearly identifiable spectral
features. Quality 1 means that no redshift is available.
Note (5): An integer used to identify spectra that have problems that might
compromise the ability to measure a redshift or line indices of a
spectrum. code as follows:
1 = Mild slit contamination or artefacts that should not strongly affect
measurements.
2 = Non-galaxy-like spectrum and/or image.
4 = Significant slit contamination from neighbouring objects. Redshift and
features may be compromised.
8 = Poor telluric correction or sky subtraction, due, for example, to
inadequate correction for the stray light effect described in Appendix B.
16 = Major artefacts or large masked regions that render the spectrum nearly
useless.
Flags can be added. So, for example, a flag of 12 means that there is
both contamination from neighbouring objects and poor sky subtraction.
Note (6): The noise estimate is taken from the VAR array associated with the
spectrum.
Note (7): The noise estimate is taken from the rms in the science spectrum
over the same range.
Note (8): The equivalent width of the line and its uncertainty, in Å,
using the line index definitions in Balogh+ (1999). See Section 4.2.2.
Note (9): Calculated from the Gaussian fitting model described in Old+ (2020).
Note (10): The SFR in solar masses per year, estimated from the [OII] emission
line flux and the stellar mass, using the calibration of Gilbank+ (2010).
Note (11): Applicable only to the 11 SPT and SpARCS clusters in GOGREEN, this
indicates likely cluster membership based on the CLEAN algorithm of
Mamon+ (2013MNRAS.429.3079M 2013MNRAS.429.3079M). A value of 1 indicates a member, 0 is a
non-member, and -1 indicates that membership could not be
determined.
Note (12): Applicable only to the 11 SPT and SpARCS clusters in GOGREEN, this
indicates likely cluster membership based on the C.L.U.M.P.S.
algorithm of Munari+ (in preparation). A value of 1 indicates a
member, 0 is a non-member, and -1 indicates that membership could
not be determined.
Note (13): For SpARCS and SPT clusters in GOGREEN, this is the maximum of the
"member_Clean" and "member_EM" flags. For the five GCLASS clusters, we
use the membership given in Muzzin+ (2012ApJ...746..188M 2012ApJ...746..188M). Finally,
for the systems in COSMOS and SXDF we define members as those within
1Mpc and 2.5σ of the centre, as described in Section 4.2.3.

--------------------------------------------------------------------------------
Note (1): Name of the corresponding cluster, when there is an associated
photometric catalogue. Objects in the COSMOS or SXDF photometric
catalogues are identified with those labels, unless there is a GOGREEN
spectroscopic redshift, in which case we use the name of the
associated target. Note that SXDF49 and SXDF87 share a field, and are
identified here only by SXDF49. Similarly, SXDF76a and SXDF76b are
identified here as SXDF76.
Note (2): This is a unique identifier for each object in this table. The first
digit identifies the source of the photometry (1: GOGREEN; 2: GCLASS;
3: UltraVISTA/COSMOS; 4: SPLASH/SXDF). The next two digits are the
cluster_id column from Table 2. The remaining numbers are the PHOTID
identifier in the main photometric catalogues.
Note (3): The ID corresponding to Table 4 for objects with a corresponding
GCLASS or GOGREEN spectrum.
Note (4): J2000 positions, in degrees. Calibrated with SDSS DR7 or USNO-b
whenever a cluster falls outside of the SDSS footprint.
Note (5): The quality flag for the associated spectrum, if any. Redshifts
without a corresponding Redshift_Quality are copied from the parent
(UltraVISTA or SPLASH) catalogue.
Note (6): Photometric redshift based on the zpeak output from eazy
(Brammer+ 2008), where for the GOGREEN galaxies a polynomial
correction is applied to improve the correspondence with spectroscopy.
Note (7): Rest-frame colours between Johnson U, V, and J, as measured with
eazy (Brammer+ 2008). Small offsets, as described in van der
Burg+ (2020), have been applied on a cluster-by-cluster basis to
improve correspondence with UltraVISTA. For the COSMOS galaxies, the
rest-frame colours are from the UltraVISTA catalogue.
Note (8): Manual mask at position of detection, where objects are masked
(totmask=1) if they do not have an image in all available filters for
that cluster. Only sources with totmask=0 are included in this
compilation catalogue. Photometry for other sources must be obtained
from the original catalogues.
Note (9): Total stellar masses, measured with the fast (Kriek+ 2009)
code and assuming the best redshift for the object (spectroscopic or
zphot). These assume τ-model star formation histories, and are
known to underestimate the stellar mass obtained with a non-parametric
star formation history, by up to 0.3dex (Leja+ 2019). For objects in
COSMOS and SXDF, the stellar masses are taken from their respective
catalogues.
Note (10): The total fluxes are derived from the Ks_tot flux and the
appropriate colour, computed in 2-arcsec diameter circular apertures
from PSF-matched images.
For objects in COSMOS and SXDF, the fluxes are taken from their
respective catalogues, scaled by the corresponding Ks_tot flux.
Note (11): IRAC aperture fluxes have been measured in a two-step process,
similar to the description in appendix A of van der Burg+ (2013). The
measurements within a 3-arcsec aperture are scaled by a factor
determined by comparing the 2-arcsec aperture Ks flux with that within
a 3-arcsec aperture measured on an image convolved to match the IRAC
PSF. This is done to avoid having to convolve all the high-resolution
ground-based data to the IRAC PSF.
Note (12): Associated uncertainty estimates for filters, assuming that the
sole source of uncertainty is the background rms. It therefore depends
on position on the stack (as the depth is not necessarily uniform),
but does not depend on the source flux.

Global notes:
Note (G1): The GCLASS sample of 10 massive clusters, and 9 of the clusters in
GOGREEN, is drawn from the Spitzer Adaptation of the Red Cluster
Sequence (SpARCS) Survey (Muzzin+ 2009ApJ...698.1934M 2009ApJ...698.1934M ;
Wilson+ 2009ApJ...698.1943W 2009ApJ...698.1943W and Demarco+ 2010ApJ...711.1185D 2010ApJ...711.1185D). Three
of the GOGREEN clusters (SPT0205, SPT0546, and SPT2106) were selected
from the South Pole Telescope (SPT) survey. To extend the GOGREEN
sample to lower halo masses, nine galaxy groups in the COSMOS and
Subaru-XMM Deep Survey (SXDS) were included. These were selected based
on spectroscopically confirmed detections at X-ray wavelengths, drawn
from updated versions of the catalogues described in
Finoguenov+ (2010, J/MNRAS/403/2063 and 2007, J/ApJS/172/182) and
George+ (2011, J/ApJ/742/125). See Section 2.1.
SpARCS names have been rewritten in full format name (JHHMMSS+DDMMSS)
