Detailed description of the data product¶
(TBC): This data product contains the list of the radial profiles for each cluster of the input catalogue of detected clusters. This is the main data product of the PROF-CL PF.
Keywords¶
This fits file is expected to contain the following keywords in the primary HDU, characterizing the important parameters of the product:
VERSION: software version
GALAXY_FILE: galaxy file name
METHOD: method (TNC for Truncated Newtonian Conjugate MLE, DE for Differential Evolution MLE, MED for median separation)
TOLERANCE: relative tolerance for minimization method
RECENTER_FLAG: 1 to recenter, else 0
ELLIPTICITY_FLAG: 1 for elliptical fit, else 0
RESCALE_FLAG: 1 for parameter-rescaling to relative tolerance in minimization, else 0
BACKGROUND_FLAG: 1 for uniform background added in fit, else 0
N_POINTS: > 0 for number of points for Monte-Carlo integration, <0 for -log_10(relative tolerance in quadratures)
MODEL: number density model (NFW, cNFW)
GALAXY_COLOR: galaxy color class (all, red, blue) TBD
GALAXY_COLOR_FLAG: [how to split galaxies between red and blue: easy at z=0, but not at high z] TBD
DEBLENDING_NUMBER_SUBS: number of (sub)clusters (including main component) TBD
CENTER_INIT_METHOD: method to initialize center (0 for DET-CL center, 1 for median center) TBD
(TBC): TBD
Table¶
The profclProfiles table is expected to contain the following columns, for each detected cluster:
RA_CEN_BESTFIT: best fit right ascension of cluster center (degrees)
DEC_CEN_BESTFIT: best fit declination of cluster center (degrees)
LOG_SCALE_RADIUS_BESTFIT: best fit radius of slope -2 of NFW or cNFW density profile (r_s for NFW, 2 r_s for cNFW, degrees)
ELLIPTICITY_BESTFIT: best fit ellipticity (0 for circular)
PA_BESTFIT: best fit position angle (degrees, East from North)
LOG_BACKGROUND_BESTFIT: best fit galaxy background surface density (degrees^-2)
NOFA_BESTFIT: normalization of surface number density (degrees^-2)
MINUS_LOG_LIKELIHOOD: opposite of log maximum likelihood
DEBLENDING_ORDER: rank of (sub)cluster TBD
BIC: Bayesian Information criterion
FIT_NFEV: number of function evaluations
RA_CEN_GUESS: first guess of right ascension of cluster center (degrees, from DET-CL center or from median RA)
DEC_CEN_GUESS: predicted right ascension of cluster center (degrees, from DET-CL center or from median Dec)
LOG_SCALE_RADIUS_GUESS: TBD
ELLIPTICITY_GUESS: first guess of cluster ellipticity from 2nd order moments (weighted by memebrship probabilities, 0 for circular)
PA_GUESS: first guess of cluster position angle from 2nd order moments (weighted by memebrship probabilities, degrees East from North)
LOG_BACKGROUND_GUESS: first guess of log_10 background surface density (degree^-2, taken as log(N_galaxies/area - 3)
(TBC): TBD
