DoDeblendingValidation

Introduction

The DoDeblendingValidationTask class implements the validation of the children clusters, i.e. the clusters produced by the partitioning of the parent cluster.

Algorithm

The algorithm is implemented in the do_deblending_validation() and deblend_parent() validate_children_clusters() functions.

Paramters

• validate_children: if True, then the resulting children sub-clusters are processed to be validated by the validate_children_clusters() that validates the sub-clusters, and returns the final list of accepted subclusters.
• children_compact_frac_size: children to parent fractional size in pixels, below which the children is considered compact
• children_ext_frac_size: children to parent fractional size in pixels, above which the children is considered extended
• children_bright_frac_peak_flux: fractional peak flux of the children above which the children is considered bright.(Bright sources will be validated)
• children_min_frac_integ_flux: min. val of the ratio of children to parent integ. flux, to validate an extended source children
• children_min_frac_peak_flux: the minimum fractional peak flux to validate a compact source

conf file section

The configuration file section will read:

[ task: deblending_validation: start]
    validate_children = False
    children_compact_frac_size = 0.1
    children_ext_frac_size = 0.1
    children_bright_frac_peak_flux = 0.1
    children_min_frac_integ_flux = 0.1
    children_min_frac_peak_flux = 0.1
    verbose = False
    plot = False
[ task: deblending_validation: stop]
