ADC_Keywords: Millimetric/submm sources ; Surveys Keywords: cosmology: observations - galaxies: clusters: general - catalogs 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 >103 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 Y5R500 are robust to pressure-profile variation and beam systematics, but accurate conversion to Y500 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. File Summary:

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 thetas 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 thetas 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 1014M. 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.
