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:

  1. VERSION: software version

  2. GALAXY_FILE: galaxy file name

  3. METHOD: method (TNC for Truncated Newtonian Conjugate MLE, DE for Differential Evolution MLE, MED for median separation)

  4. TOLERANCE: relative tolerance for minimization method

  5. RECENTER_FLAG: 1 to recenter, else 0

  6. ELLIPTICITY_FLAG: 1 for elliptical fit, else 0

  7. RESCALE_FLAG: 1 for parameter-rescaling to relative tolerance in minimization, else 0

  8. BACKGROUND_FLAG: 1 for uniform background added in fit, else 0

  9. N_POINTS: > 0 for number of points for Monte-Carlo integration, <0 for -log_10(relative tolerance in quadratures)

  10. MODEL: number density model (NFW, cNFW)

  11. GALAXY_COLOR: galaxy color class (all, red, blue) TBD

  12. GALAXY_COLOR_FLAG: [how to split galaxies between red and blue: easy at z=0, but not at high z] TBD

  13. DEBLENDING_NUMBER_SUBS: number of (sub)clusters (including main component) TBD

  14. CENTER_INIT_METHOD: method to initialize center (0 for DET-CL center, 1 for median center) TBD

  15. (TBC): TBD

Table

The profclProfiles table is expected to contain the following columns, for each detected cluster:

  1. RA_CEN_BESTFIT: best fit right ascension of cluster center (degrees)

  2. DEC_CEN_BESTFIT: best fit declination of cluster center (degrees)

  3. 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)

  4. ELLIPTICITY_BESTFIT: best fit ellipticity (0 for circular)

  5. PA_BESTFIT: best fit position angle (degrees, East from North)

  6. LOG_BACKGROUND_BESTFIT: best fit galaxy background surface density (degrees^-2)

  7. NOFA_BESTFIT: normalization of surface number density (degrees^-2)

  8. MINUS_LOG_LIKELIHOOD: opposite of log maximum likelihood

  9. DEBLENDING_ORDER: rank of (sub)cluster TBD

  10. BIC: Bayesian Information criterion

  11. FIT_NFEV: number of function evaluations

  12. RA_CEN_GUESS: first guess of right ascension of cluster center (degrees, from DET-CL center or from median RA)

  13. DEC_CEN_GUESS: predicted right ascension of cluster center (degrees, from DET-CL center or from median Dec)

  14. LOG_SCALE_RADIUS_GUESS: TBD

  15. ELLIPTICITY_GUESS: first guess of cluster ellipticity from 2nd order moments (weighted by memebrship probabilities, 0 for circular)

  16. PA_GUESS: first guess of cluster position angle from 2nd order moments (weighted by memebrship probabilities, degrees East from North)

  17. LOG_BACKGROUND_GUESS: first guess of log_10 background surface density (degree^-2, taken as log(N_galaxies/area - 3)

  18. (TBC): TBD
