*Abstract*:
The quest for the cosmological parameters that describe our universe
continues to motivate the scientific community to undertake very large
survey initiatives across the electromagnetic spectrum. Over the past
two decades, the Chandra and XMM-Newton observatories have sup- ported
numerous studies of X-ray-selected clusters of galaxies, active
galactic nuclei (AGNs), and the X-ray background. The present paper is
the first in a series reporting results of the XXL-XMM survey; it
comes at a time when the Planck mission results are being finalised.
We present the XXL Survey, the largest XMM programme totaling some
6.9Ms to date and involving an international consortium of roughly 100
members. The XXL Survey covers two extragalactic areas of 25deg^2
each at a point-source sensitivity of ?5x10^-15 erg/s/cm^2 in the
[0.5-2]keV band (completeness limit). The survey's main goals are to
provide constraints on the dark energy equation of state from the
space-time distribution of clusters of galaxies and to serve as a
pathfinder for future, wide-area X-ray missions. We review science
objectives, including cluster studies, AGN evolution, and large-scale
structure, that are being conducted with the support of approximately
30 follow-up programmes.

*Description*:
Paper I. Scientific motivations - XMM-Newton observing plan.
Follow-up observations and simulation programme.
The table xxlpoint.dat is a list of all XMM survey-type observations
(?AO-10) in the XXL fields, providing the match between the internal
naming and the ESA XXM log,the coordinates and useful exposure times
of the XMM pointings, their quality and ancillary information.
Paper II. The bright cluster sample: catalogue and luminosity function.
Paper III. Luminosity-temperature relation of the bright cluster sample.
Paper IV. Mass-temperature relation of the bright cluster sample.
This article presents the XXL bright cluster sample, a subsample of
100 galaxy clusters selected from the full XXL catalogue by setting a
lower limit of 3*10^-14 erg/cm^2 /s on the source flux within a 1'
aperture.
The selection function was estimated using a mixture of Monte Carlo
simulations and analytical recipes that closely reproduce the source
selection process. An extensive spectroscopic follow-up provided
redshifts for 97 of the 100 clusters. We derived accurate X-ray
parameters for all the sources. Scaling relations were
self-consistently derived from the same sample in other publications
of the series. On this basis, we study the number density, luminosity
function, and spatial distribution of the sample.
The bright cluster sample consists of systems with masses between
M_500 =7*10^+14 and 3*10^+14 M_? , mostly located between z=0.1
and 0.5. The observed sky density of clusters is slightly below the
predictions from the WMAP9 model, and significantly below the
prediction from the Planck 2015 cosmology. In general, within the
current uncertainties of the cluster mass calibration, models with
higher values of ?_8 and/or ?_M appear more difficult to
accommodate. We provide tight constraints on the cluster differential
luminosity function and find no hint of evolution out to z?1. We also
find strong evidence for the presence of large-scale structures in the
XXL bright cluster sample and identify five new superclusters.
We provide the XXL-100-GC catalogue (xxl100gc.dat), the master
catalogue of the 100 brightest galaxy clusters from the XXL Survey.
This catalogue summarizes all the information published on this sample
by the XXL collaboration, which were initially distributed over
several articles. It contains the sources positions, redshifts, fluxes
and mass estimates published in Appendix D of paper II, combined with
luminosities and temperatures from Table 1 of paper III, as well as
gas masses from Table A.1 of paper XIII.
Paper VI. The 1000 brightest X-ray point sources.
We provide the XXL_1000 AGN catalogue (xxl1000a.dat), the first
catalogue release of the XXL point source catalog, detected in the
2-10keV energy band. The catalogue contains the 1000 brightest
sources, at the flux limit of F[2-10 keV]=4.8 10^-14 erg/s/cm^2 . We
provide derived X-ray spectral parameters, and counterpart properties
including four optical magnitudes, photometric and spectroscopic
redshift estimates. We also provide the best photometric redshift
class based on machine learning classification and the probability for
a source to be a star or a photometric redshift outlier.
Paper IX. Optical overdensity and radio continuum analysis of a
supercluster at z=0.43.
The table xxl_vla.dat contains the full source catalogue of all 155
radio sources detected with S/N?6 in the Very Large Array 3GHz
continuum survey of the XXL-North field. The observations covered the
0.7x0.7 square degrees subarea of the 25 square degree XXL-North
field. The radio data has an angular resolution of 3.2x1.9 square
arcsec and a mean rms of 20uJy per beam. There are 25 resolved
sources, of which 8 are multicomponent objects.
Paper XI. ATCA 2.1 GHz continuum observations.
The table xxl_atca.dat contains the full source catalogue of all 1389
radio sources detected with S/N?5 in the Australia Telescope Compact
Array 2.1GHz continuum pilot survey of the XXL-South field. The
observations covered the inner 6.5 square degrees of the 25 square
degree XXL-South field. The radio data has an angular resolution of
4.7x4.2 square arcsec and a median rms of 50uJy per beam. There are
305 resolved sources, of which 77 are multicomponent objects. The
table contains various observed parameters of the radio sources, such
as position, peak flux density and signal-to-noise ratio.
Paper XIV. AAOmega redshifts for the southern XXL field.
We present a catalogue (xxlaaoz.dat) containing the redshifts of 3660
X-ray selected targets in the XXL southern field. The redshifts were
obtained with the AAOmega spectrograph and 2dF fibre positioner on the
Anglo-Australian Telescope. The catalogue contains 1515 broad line
AGN, 528 stars, and redshifts for 41 out of the 49 brightest X-ray
selected clusters in the XXL southern field.
Paper XV. Evidence for dry merger driven BCG growth in XXL-100-GC X-ray
clusters
Given the availability of good quality multiband photometry together
with photometric and spectroscopic redshifts to z<1, a simple set of
criteria can be used to identify BCGs. For the present work, we define
a BCG as:
- the brightest galaxy in z-band,
- within 0.5xr500 of the cluster X-ray centroid,
- with a redshift that is consistent with that of the cluster as
determined from all the redshifts available around the X-ray
centroid.
Our final sample (xxl100bc.dat) consists of 85 clusters, 45 of which
are in the Northern field and 40 in the Southern field.

*Note (1)*: XXLn or XXLs stand for the XXL-N (XXL-S) field;
a,b,c... tags indicate that the same a,b,c... tags indicate that the same
sky position has been observed several times in different AOs (consult the ESA
XMM log using the ESA ObsId) because the quality of earlier pointings was
insufficient; the z tag means that a fictitious pointing has been created
combining the events of all usable repeated pointings, in order to improve
the quality. In total there are 542 and 81 a,b,c and z pointings respectively.
In case of repeated fields, as well as of overlaps from adjacent fields, the
X-ray catalogue will remove overlapping detections, and consider only the one
from the better pointing, or, in case of equal quality, the object with the
smallest off-axis angle.
*Note (2)*: The exposure for the MOS and pn detectors is the remaining
exposure (in ks) after selection of the good-time intervals.
*Note (3)*: Quality flag as follows:
0 = good quality
1 = low exposure
2 = high background
3 = low exposure and high background
*Note (4)*: Badfield flag as follows:
0 = best acceptable observation at a given position
1 = for deep/good observation from the archives, not part of XXL proper
2 = other acceptable XXL observation at same position
3 = bad pointings i.e. quality=3
This flag is used in the overlap removal procedure
*Note (5)*: This column is ticked if Xamin detected at least one object in this
pointing.
*Note (6)*: This column is ticked if at least one source in this pointing survived
the overlap removal procedure and hence entered the X-ray source catalogue.
