Detailed Description of the Data Product¶

This HDU gives the probability that a cluster with a richness lambda_true and a redshift_true is detected with at lambda_obs and redshift_obs, , and the associated statistical errors. These two datasets appear in two distinct HDUs, with identical header content and identical table format.

Keywords¶

These keywords should define the sky area, the quantities associated with the clusters detection, and the associated selection cuts from which the subsample is built. The default scheme is that the TRUE and OBS quantities have the same binning (TBC).

AREA_MASK: Reference to a visibility or footprint mask defining the target sky area
Z_KEY: Name of the redshift column used for the subsample
RICHNESS_KEY: Name of the richness column (i.e. LAMBDA) used for the subsample
Z_TRUE_START: Lower value of binning in Z_TRUE
Z_TRUE_END: Upper value of binning in Z_TRUE
Z_TRUE_STEP: Step value of binning in Z_TRUE
Z_OBS_START: Lower value of binning in Z_OBS
Z_OBS_END: Upper value of binning in Z_OBS
Z_OBS_STEP: Step value of binning in Z_OBS
LAMBDA_TRUE_START: Lower value of binning in LAMBDA_TRUE
LAMBDA_TRUE_END: Upper value of binning in LAMBDA_TRUE
LAMBDA_TRUE_STEP: Step value of binning in LAMBDA_TRUE
LAMBDA_OBS_START: Lower value of binning in LAMBDA_OBS
LAMBDA_OBS_END: Upper value of binning in LAMBDA_OBS
LAMBDA_OBS_STEP: Step value of binning in LAMBDA_OBS

Tables¶

Each of these two tables has NBins(LAMBDA_TRUE) columns and NBins(Z_TRUE) lines. Each table cell contains a matrix oof NBins(LAMBDA_OBS columns and NBins(Z_OBS) lines.

First HDU:

PROB_LAMBDA_Z_OBS_TRUE : Probability to detect a hypothetical cluster of richness LAMBDA_OBS and redshift Z_OBS, as a function of quantities LAMBDA_TRUE and Z_TRUE
