Detailed Description of the Data Product¶
This product stores configuration parameters for SEL, including that paths to 1 or more selection files.
Each selection file contains the criteria to define a sample. A selection can include a redshift range and cuts on any columns in the catalog.
Format of the selection file¶
The selection file is a xml file and it specifies metadata about the product (such as ProductId, creation date,dataset release, etc).
The configuration includes three main selection components:
MainSelection (EWS_Main): Represents the primary wide survey selection.
DeepSelection (EDS_Main): Represents the deep survey selection.
SampleSelection: Defines a specific sample selection used, referencing: a selection configuration file (e.g. sel_selection_20260304_SplitNS_1.yaml) and a machine learning model file (e.g. starcounts_gaia_TR1_20251114.fits)
Each selection corresponds to a SQL-like query that filters sources based on criteria imposed on the columns’ names.
The configuration is labeled as BaseSelection and uses the Default cosmology model.
Metadata¶
The configuration is stored in the metadata in the follwing elements.
