Detailed Description of the Data Product

This product contains a FITS table mapping the bias corection cells with the mean spec-z of the calibration field objects. It is produced outside the Euclid pipeline and it is used to compute the shift in redshift to correct for the PHZ bias.

Processing Element(s) creating/using the data product

• This product is produced outside the Euclid pipeline and is manually ingested in the EAS.

• It is used to compute the shift in redshift to correct for the PHZ bias.

Processing function using the data product

• PHZ PF intermediary product.

The table is expected to follow the format described by the phz.meanSpecZBiasMap version 0.9 description, which defines the following columns:

Column name	Description	Unit
OBJECT_ID	The object identifier	NA
SOM_CELL_ID	The SOM cell s identifier	NA
TOM_BIN_ID	Tomographic bin s identifier	NA
ALT_TOM_BIN_ID	Alternate Tomographic bin s identifier	NA
NO_WEIGHT	The weight of the object (uniformly 1)	NA
PHZ_WEIGHT	The PHZ weight of the object	NA
KSB_WEIGHT	The KSB weight of the object	NA
LENS_MC_WEIGHT	The LENS_MC weight of the object	NA
MOMENTS_ML_WEIGHT	The MOMENTS_ML weight of the object	NA
REGAUSS_WEIGHT	The REGAUSS weight of the object	NA
GAL_SPEC_Z	The specz of the object	NA
GAL_SPEC_Z_ERR	The error on the specz of the object	NA

This product is used along with the CoAddedPDZBiasMap in the PHZ Bias Correction pipeline to produce the PHZ bias correction map.
