Detailed Description of the Data Product
_________________________________________
.. DetailedDescStart

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
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. PECreatorStart

* 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
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
.. PFUsingStart

* PHZ PF intermediary product.

.. PFUsingEnd

The table is expected to follow the format described by the
phz.meanSpecZBiasMap version 0.1 description, which
defines the following columns:

#. **BIAS_ID**: The bias correction identifier
#. **SPEC_Z**: The mean spectroscopic redshift for callibration sources
   belonging this bias identifier.

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