Abstract:
We present the all-sky Planck catalogue of Sunyaev-Zeldovich (SZ)
sources detected from the 29 month full-mission data. The catalogue
(PSZ2) is the largest SZ-selected sample of galaxy clusters yet
produced and the deepest systematic all-sky survey of galaxy clusters.
It contains 1653 detections, of which 1203 are confirmed clusters with
identified counterparts in external data sets, and is the first
SZ-selected cluster survey containing >10^3^ confirmed clusters. We
present a detailed analysis of the survey selection function in terms
of its completeness and statistical reliability, placing a lower limit
of 83% on the purity. Using simulations, we find that the estimates of
the SZ strength parameter Y_5R500_ are robust to pressure-profile
variation and beam systematics, but accurate conversion to Y_500_
requires the use of prior information on the cluster extent. We
describe the multi-wavelength search for counterparts in ancillary
data, which makes use of radio, microwave, infrared, optical, and
X-ray data sets, and which places emphasis on the robustness of the
counterpart match. We discuss the physical properties of the new
sample and identify a population of low-redshift X-ray under-luminous
clusters revealed by SZ selection. These objects appear in optical and
SZ surveys with consistent properties for their mass, but are almost
absent from ROSAT X-ray selected samples.
Description:
Three pipelines are used to detect SZ clusters: two independent
implementations of the Matched Multi-Filter (MMF1 and MMF3), and
PowellSnakes (PwS). The main catalogue is constructed as the union of
the catalogues from the three detection methods. The completeness and
reliability of the catalogues have been assessed through internal and
external validation as described in section 4 of the paper.

Note (1): Format is PSZ2 Glll.ll+bb.b where (l,b) are the Galactic coordinates
truncated to 2 decimal places.
Note (2): The three least significant decimal digits are used to represent
detection or non-detection by the pipelines.
Order of the digits: hundreds = MMF1; tens = MMF3; units = PwS.
If it is detected then the corresponding digit is set to 1,
otherwise it is set to 0.
Note (3): Neural network quality flag is 1-Qbad, following the definitions in
Aghanim et al. 2014.
Note (4): Summary of the external validation, encoding the most robust external
identification as follows:
10 = ENO follow-up
11 = RTT follow-up
12 = PanSTARRs
13 = RedMAPPer non-blind
14 = SDSS high-z
15 = AMI
16 = WISE
20 = legacy identification from the PSZ1
21 = MCXC
22 = SPT
23 = ACT
24 = RedMAPPer
25 = legacy identification from PSZ1 with externally updated redshift
30 = NED
-1 = no known external counterpart
Note (5): Redshift source is the most robust external identification listed
in the VALIDATION field.
Note (6): MSZ is the hydrostatic mass assuming the best-fit Y-M scaling
relation of Arnaud 2010 as a prior.
The uncertainties are statistical and based on the Planck measurement
uncertainties only.
Not included in the uncertainties are the statistical errors on the scaling
relation, the intrinsic scatter in the relation, or systematic errors in
data selection for the scaling relation fit.
Note (7): Assigned by visual inspection as follows:
0 = no significant galaxy overdensity
1 = possible galaxy overdensity
2 = probable galaxy overdensity
3 = significant galaxy overdensity detected
-1 = possible galaxy overdensity (affected by bright star artefacts)
-2 = no significant galaxy overdensity (affected by bright star artefacts)
-3 = no assessment possible (affected by bright star artefacts)
-10 = not analysed
Note (8): Defined in the paper.

Note (1): Format PSZ2 Glll.ll+bb.bb where (l, b) are the Galactic coordinates
truncated to 2 decimal places.
Note (2): Extension 2 contains a three-dimensional image with the
two-dimensional probability distribution in theta_s_ and Y for
each detection.
The probability distributions are evaluated on a 256x256 linear grid between
the limits specified in extension 1. The limits are determined independently
for each detection. The dimension of the 3D image is 256x256xNdet, where
Ndet is the number of detections. The first dimension is theta_s_ and the
second dimension is Y.
Extension 3 contains a three-dimensional image with the information
on the MSZ observable per cluster as a function of assumed redshift.
The image dimensions are 100x4xNdet, where Ndet is the number of detections.
The first dimension is the assumed redshift. The second dimension has size 4:
the first element is the assumed redshift value corresponding to the MSZ
values. The second element is the MSZ lower 68% confidence bound, the third
element is the MSZ estimate and the fourth element is the MSZ upper 68%
confidence bound, all in units of 10^14^M_{sun}_. These uncertainties are
based on the Planck measurement uncertainties only. Not included in the error
estimates are the statistical errors on the scaling relation, the intrinsic
scatter in the relation, or systematic errors in data selection for the
scaling relation fit.
