DetailedDescStart This output product contains the catalog of DET-CL candidate clusters XML Keywords ^^^^^^^^^^^^ The metadata provided with the output FITS contains the following keywords: KEYWORDS COMMON TO BOTH DETECTION CODES: GENERAL PARAMETERS #. **MIN_Z**: lower limit of redshift range for cluster detection #. **MAX_Z**: upper limit of redshift range for cluster detection #. **SNR_THR**: the S/N threshold for extracting a detection KEYWORDS SPECIFIC TO AMICO DETECTION CODE: #. **CUBE_XY_STEP**: size of the RA and Dec bin [deg] #. **MAX_AREA_DEG**: Maximum area for a single tile on which AMICO can run [deg^2] #. **L_BORDER_DEG**: Size of the border defining the detection area [deg] KEYWORDS SPECIFIC TO PZWAV DETECTION CODE: #. **DZ**: half width of reach redshift slice #. **ZSTEP**: interval between slices #. **KRN_SCL1**: lower scale of kernel, in kpc #. **KRN_SCL2**: larger scale of kernel, in kpc #. **DR_LIM**: radius of matching area for the merging of detected peaks, in kpc #. **DZ_LIM**: redshift depth for the merging of detected peaks COSMOLOGY PARAMETERS KEYWORDS: #. **OMEGA_MAT**: matter energy density #. **OMEGA_VAC**: vacuum energy density #. **HUBBLE_PAR**: Hubble constant in km/s/(Mpc/h) #. **W_EQ_STATE**: dark energy equation of state #. **N_EFF**: effective number of relativistic species #. **TEMP_CMB**: CMB temperature Note : Currently, a flat LCDM model is assumed, depending only on HUBBLE_PAR and OMEGA_MAT. The list above allows a broader choice for the cosmological model (wCDM). KEYWORDS FOR RICH-CL TO MOVE TO THE CCP PIPELINE: #. **MAX_NB**: Maximum number of structures to which a galaxy can be associated #. **MIN_PROB**: Minimum probability for the association to be saved Clusters FITS file ^^^^^^^^^^^^ The FITS file produced by DET-CL contains the following keywords: Keywords +++++++++++++ This fits file is expected to contain the following keywords in the data table HDU, characterising the main parameters of the "clusters detection" product.
