========================================
.. DetailedDescStart

The data product is a container for the individual FITS files that hold the
position-position, position-shear, and shear-shear covariance matrices.

The *Data* element of type *pKWLCovMatrix2D* contains the following fields (see
schema__):

__ https://gitlab.euclid-sgs.uk/ST-DM/ST_DataModel/-/blob/develop/ST_DM_Schema/auxdir/ST_DM_Schema/dictionary/pro/le3/wl/pk/euc-test-le3-wl-pk.xsd

CovMatrixPosPos : le3.wl.pk.output.covmatrixpospos2d
    FITS file with position-position covariance matrix components.

CovMatrixPosShear : le3.wl.pk.output.covmatrixposshear2d
    FITS file with position-shear covariance matrix components.

CovMatrixShearShear : le3.wl.pk.output.covmatrixshearshear2d
    FITS file with shear-shear covariance matrix components.

If one of the covariance matrices has not been requested from the pipeline, the
corresponding field does not exist.

For the definitions of the FITS file formats, see the `FITS schema`__.
