PLANCKSZ2 - Planck 2nd Sunyaev-Zeldovich Source Catalog |
HEASARC Archive |
Three pipelines were used to detect SZ clusters: two independent implementations of the Matched Multi-Filter (MMF1 and MMF3) and PowellSnakes (PwS). The main catalog contained in this HEASARC table is constructed as the union of the catalogs from the three detection methods. The completeness and reliability of the catalogs have been assessed through internal and external validation as described in section 4 of the reference paper.
The HEASARC has changed the names of many of the parameters from those given in the original table. In such cases we have listed the original names in parentheses at the end of the parameter descriptions given below.

is the Galactic longitude and +yy.yy (or -yy.yy) is the Galactic latitude of
the detection, both in degrees.

J2000.0 decimal degrees to a precision of 10-7 degrees in the original
table.
LII

Ref_Pipeline_Code
The reference code for the pipeline from which the source information in this
union catalog was taken, where 1= MMF1, 2 = MMF3, and 3 = PwS, 1 and 2 being
two independent implementations of the Matched Multi-Filter detection
algorithm, and 3 the PowellSnakes (PwS) detection algorithm. (PIPELINE)
Det_Pipeline_Codes
This parameter contains a code that is used to indicate which pipelines
detected this object. The three least significant decimal digits are used to
represent detection or non-detection by the pipelines. The order of the
digits is as follows: hundreds = MMF1; tens = MMF3; and ones = PwS. If a
source is detected by a particular pipeline then the corresponding digit is
set to 1, otherwise it is set to 0. (PIPE_DET)
PCCS2_Match
This flag parameter is set to 1 to indicate that the SZ detection has a
matching source in the Second Planck Catalogue of Compact Source (PCCS:
Planck Collaboration 2016, A&A, 594, A26) single-frequency catalogs, else is
set to 0. (PCCS2)
PSZ1_Match
The source number (index) of the matching SZ detection in the PSZ1 Catalog
(Planck Collaboration 2014, A&A, 571, A29, or -1 if the PSZ2 source is a new
detection. (PSZ)
IR_Contam_Flag
This flag parameter is set to 1 to indicate that the SZ detection is in a
region of heavy IR contamination, else is set to 0. (IR_FLAG)
Nn_Quality_Flag
This parameter contains the neural network quality flag value for the SZ
source, 1-Qbad , following the definitions in Aghanim et al. (2015, A&A,
580, A138). Values less than 0.4 denote low-reliability detections.
(Q_NEURAL)
Y5R500
The mean marginal Y5R500 for the SZ source detection as determined by the
reference pipeline, in units of arcmin2. This parameter, the integrated
blind flux, is defined in Section 2.1 and equation (5) of the reference
paper.
Y5R500_Error
The uncertainty in the mean marginal Y5R500 for the SZ source detection as
determined by the reference pipeline, in units of arcmin2.
Validation_Status
This parameter (VALIDATION) contains a summary of the external validation
status of the SZ detection, encoding the most robust external identification,
with the following possible values:
Value Meaning -1 no known external counterpart; 10 European Northern Observatory (ENO) follow-up; 11 Russian-Turkish 1.5 m telescope (RTT) follow-up; 12 PanSTARRs; 13 redMaPPer non-blind; 14 SDSS high-z; 15 Arcminute Microkelvin Imager (AMI); 16 WISE; 20 legacy identification from the PSZ1 2013 release; 21 Meta-Catalogue of X-ray detected Clusters of galaxies (MCXC, Piffaretti et al. 2011); 22 South Pole Telescope (SPT); 23 Atacama Cosmology Telescope (ACT); 24 redMaPPer; 25 PSZ1 counterpart with redshift updated in Planck Collaboration XXXII (2015); 30 NED.
Redshift
The redshift of the cluster of galaxies.
Redshift_Source_Name
The external identifier of the cluster associated with the redshift
measurement. The redshift source is the most robust external validation
listed in the validation_status parameter. (REDSHIFT_ID)
Mass_SZ
The SZ mass proxy, MSZ, in units of 1014 solar masses. This is defined as
the hydrostatic mass, M500, assuming the Y-M scaling relation of Eq. (7) of
Planck Collaboration XX (2014, A&A, 571, A20) as a prior that cuts a plane
through the parameter contours (see Sect. 5.3 of the reference paper). The
assumed cosmology for this calculation is h = 0.7, OmegaM = 0.3 and
OmegaLambda = 0.7. (MSZ)
Mass_SZ_Pos_Err
The upper 67% confidence statistical error based on the Planck measurement
uncertainties only of the SZ mass proxy, MSZ, in units of 1014 solar
masses. 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. (MSZ_ERR_UP)
Mass_SZ_Neg_Err
The lower 67% confidence statistical error based on the Planck measurement
uncertainties only of the SZ mass proxy, MSZ, in units of 1014 solar
masses. 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. (MSZ_ERR_LOW)
MCXC_Name
The name of the X-ray counterpart to the SZ source in the Meta-Catalogue of
X-ray detected Clusters of galaxies (MCXC, Piffaretti et al. 2011, A&A, 534,
A109), if one is present. (MCXC)
RedMAPPer_Name

SPT_Name
The name of the SZ counterpart in the SPT catalogs, if one is present. (SPT)
WISE_Flag
A confirmation flag of the WISE IR overdensity assigned by visual inspection
and defined to be one of [-10, -3, -2, -1, 0 , 1, 2, 3], where -10 denotes no
information and the other values (discussed in Sect. 7.4 of the reference
paper) have the following meanings:
Value Meaning 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 artifacts) -2 no significant galaxy overdensity (affected by bright star artifacts) -3 no assessment possible (affected by bright star artifacts)
AMI_Det_Significance
The Bayesian evidence for the AMI counterpart detection. This is defined in
Sect. 7.5.3 of the reference paper. The HEASARC notes that there are 1,393
entries in this catalog that have values of -1.0e03 for this parameter, and
an additional 100 values that have values of -1.0e02 for this parameter, that
appear to be equivalent to null values, leaving only 160 entries with
physically plausible values. (AMI_EVIDENCE)
Cosmology_Sample_Flag
This flag parameter is set to 1 to indicate that the cluster of galaxies
associated with the SZ source is in the cosmology sample used in Paper XXIV
(Planck Collaboration 2016, A&A, 594, A24) of the Planck 2015 results sets of
paper, else is set to 0. (COSMO)
